April 2017 edit: Updated to 4.7.0

As linked in the comments on your question, Font Awesome provides a Cheatsheet page which lists all icon previews, class names and character codes and even lists aliases (fa-automobile, for instance, which is an alias of fa-car).

4.*.* Cheatsheet: http://fortawesome.github.io/Font-Awesome/cheatsheet
3.2.1 Cheatsheet: http://fortawesome.github.io/Font-Awesome/3.2.1/cheatsheet

There are a total of 593 icon class names (including aliases) in version 4.3.0. Here is the list in the format you desire (including aliases, but with no " (alias)" comments):

Solution 2:^[2]

Another little script for posterity.

Update 02/2018 (version 5.x)

Latest working version, based on edit from Blasius Secondus (thanks).

Open the fonts cheat sheet and run the following snippet in the developper console: https://fontawesome.com/cheatsheet

var names = new Set();
var icons = document.getElementsByClassName('icon');
for (const icon of icons) {
  const name = icon.getElementsByTagName('dd')[0].innerText;
  names.add(name);
}
console.log(JSON.stringify(Array.from(names)));

If you want them sorted by section (solid/regular/brand):

var groups = {};
var sections = document.getElementsByClassName('cheatsheet-set');
for (const section of sections) {
  const names = [];
  groups[section.id] = names;
  var icons = section.getElementsByClassName('icon');
  for (const icon of icons) {
    const name = icon.getElementsByTagName('dd')[0].innerText;
    names.push(name);
  }
}
console.log(groups); // Feel free to stringify/manipulate

Original answer

Simply open the latest cheatsheet: http://fortawesome.github.io/Font-Awesome/cheatsheet/

Then in your browser, open the developer console and run:

var names = [];
$('.row .col-md-4').each(function() {
  var s = $(this).text();
  var m = s.match(/fa-.*/);
  if (m && m[0] && s.indexOf('(alias)') < 0) {
    names.push(m[0]);
  }
});
console.log( JSON.stringify( names ) );

If you want the list instead of an array, replace the last line by

console.log( names.join(' ') );

(You can use any separator you want instead of space ' ')

The advantage of this method is that you will only get the visual icons (not the fa-spin and friends), and not the duplicate aliases.

Solution 3:^[3]

Better yet, you can make use of the yml file containing the icon name, its unicode and even its keywords: https://github.com/FortAwesome/Font-Awesome/blob/master/src/icons.yml

Then just use the js-yaml parser and thats it!

$.get('https://rawgit.com/FortAwesome/Font-Awesome/master/src/icons.yml', function(data){    
    var parsedYaml = jsyaml.load(data);
    var body = $('body');

    $.each(parsedYaml.icons, function(index, icon){
        body.append('<i class="fa fa-' + icon.id + '"></i>');
    })
});

Reproduction online

With a bit more of work you can even categorize icons or even create a search box for them based on their keywords.

Update 2020:

This can now be found in .json here: https://github.com/FortAwesome/Font-Awesome/tree/master/metadata

Solution 4:^[4]

First load all icons from font awesome 5 icons.

now go to developer console and paste following code

var nodes = document.querySelectorAll('i')
var icons = [];
nodes.forEach(a => icons.push( a.getAttribute('class') ) )
copy(icons)

all font awesome icons now copied in your clipboard.

Solution 5:^[5]

A very, very easy and handy way to dynamically get all FA icon classes, if you are using npm and @fortawesome/fontawesome-svg-core npm package (tested at least with version v1.2.x), is the following:

import { library } from '@fortawesome/fontawesome-svg-core'
import { fas } from '@fortawesome/free-solid-svg-icons'

// You need to add the entire icon set
library.add(fas)

let fasArray = Object.keys(library.definitions.fas)

With just few lines of code, you'll get an array of all icon classes in solid library, with values like:

[ "ad", "address-book", "address-card", "adjust", "air-freshener", "align-center", "align-justify", "align-left", "align-right", "allergies", "ambulance", "american-sign-language-interpreting", "anchor" ....]

For all (solid + regular + brand) icon libraries, you can instead use:

import { library } from '@fortawesome/fontawesome-svg-core'
import { fas } from '@fortawesome/free-solid-svg-icons'
import { far } from '@fortawesome/free-regular-svg-icons'
import { fab } from '@fortawesome/free-brands-svg-icons'

// Add both three icon sets
library.add(fas, far, fab)

let fasArray = Object.keys(library.definitions.fas)
let farArray = Object.keys(library.definitions.far)
let fabArray = Object.keys(library.definitions.fab)

With these arrays, you can build whatever JSON or object structure you want to fit your purpose.

One note to mention, library.definitions property seems to not be an official way to get access to all icons in the package, so maybe in future package versions, this snippet might not work; however a quick look at the package's source, it seems somehow unlikely they might replace it, at least without a major restructuring and different versioning.

A second note is that, if you want the array to be dynamic, you have to import the entire icon sets, which might not be something you'd like to do. Otherwise, you can run it once, get the results and use them statically.

Solution 7:^[7]

For future updates, copy paste the complete list from the cheatsheet (http://fortawesome.github.io/Font-Awesome/cheatsheet/) into an editor (notepad++ in my case). And do the following regular expression find & replace actions :

remove the special character at the begin and the characters between block quotes []

find: ^.*(fa-[^\s]*).*
replace: \1

and if you want to wrap everything in an array:

find: ^.*(fa-[^\s]*).*
replace: "\1",

you only need to start the string with "[" and end it with "]" to make the array complete

Solution 8:^[8]

Here is a snippet that works based on the loaded css. It assumes you have loaded the stylesheet with a name of font-awesome.css among other things but you could tweak this for your use. Theoretically, this will continue to work as future versions of font-awesome are released and new icons are added. That of course assume he keeps the css consistent over time.

var icons = $.map($.map(document.styleSheets, function(s) { 
    if(s.href && s.href.endsWith('font-awesome.css')) 
        return s; 
    return null; 
})[0].rules, function(r) { 
    if(r.cssText.indexOf('::before { content: ') > 0) 
        return r.cssText.substring(4,r.cssText.indexOf('::')); 
    return null; });

Solution 9:^[9]

Using PHP and the official icons.json file:

function fa_icons () {
    $content = file_get_contents('https://raw.githubusercontent.com/FortAwesome/Font-Awesome/master/metadata/icons.json');
    $json = json_decode($content);
    $icons = [];

    foreach ($json as $icon => $value) {
        foreach ($value->styles as $style) {
            $icons[] = 'fa'.substr($style, 0 ,1).' fa-'.$icon;
        }
    }

    return $icons;
}

Returns:

Array
(
    [0] => fab fa-500px
    [1] => fab fa-accessible-icon
    [2] => fab fa-accusoft
    [3] => fas fa-address-book
    [4] => far fa-address-book
    [5] => fas fa-address-card
    ...

how to get Font Awesome Icons in a JSON object grouped by categories

I made this to use with the excellent jQuery fontIconPicker

Done with with FA Version 5.0.6

JSON result is available at https://gist.github.com/migliori/60154172ba0eea70e3c0dd4c3b5d82d0 for lazy people.

Navigate to https://fontawesome.com/icons?d=gallery&m=free

Paste this code in your browser console to grab the available categories and their icons. Wait about 2 minutes and it will return them into a JSON Object

if(typeof endList == 'undefined') {
    var endList         = new Object();
    var catList         = document.getElementsByClassName('fa-ul')[2];
    var catListElements = catList.getElementsByTagName('li');
    var catListLength   = catListElements.length;
    console.log(catListLength);
    var i;

    var getIcons = function(el) {
        var classes = new Array();
        var name    = el.innerText;
        console.log(name);
        var icons   = document.getElementById('results-icons').getElementsByTagName('svg');
        for (var icon of icons) {
          var clazz = icon.getAttribute('data-prefix') + ' fa-' + icon.getAttribute('data-icon');
          classes.push(clazz);
        }
        console.log(classes);
        console.log('-----');
        endList[name] = classes;

        if(i + 1 < catListLength) {
            el.getElementsByClassName('relative')[0].click();
            i++;
            setTimeout(getCategory, 3000);
        } else {
            console.log(JSON.stringify(endList));
        }

        return;
    }

    var getCategory = function() {
        var el = catListElements[i];
        el.getElementsByClassName('relative')[0].click();
        setTimeout(function() {
            getIcons(el);
        }, 3000);
    }
}
i = 0;
getCategory();

Solution 13:^[13]

In case someone would like to have Font awesome icons grouped just like in http://fontawesome.io/icons/. Paste this to JS console on icons screen of FA.

var allIcons = {};
$('#icons section:not(#new):not(#spinner)').each(function(key, item) {
    var name = $(item).attr('id');

Park's answer is almost right. However, sometimes there are more than one icon assigned to the same content for backwards compatibility. This script will take that into consideration:

var icons = $.map($.map(document.styleSheets,
                function(s) {
                    if (s.href && s.href.endsWith('font-awesome.css'))
                        return s;
                    return null;
                })[0].rules,
            function(r) {
                var result = [];
                if (r.cssText.indexOf('::before { content: ') > 0) {
                    $.each(r.cssText.split(','),
                        function (i, item) {
                            result.push(item.split(':')[0].trim().substring(4));
                        });
                }
                return result;
            });

This one is more like floribon's answer but in vanilla JS.

Head over to Font Awesome Cheatsheet, fire up the console and write.

var q=document.querySelectorAll('.row .col-md-4')
var names = []
for (var i=0;i<q.length;i++){
try{
names.push(q[i].innerHTML.match(/\s\sfa-.*\n/).toString().trim())
}
catch(e){}
}
names=names.filter(name => name.length)
console.log(names)

PS: This is subject to change when there's a change in DOM structure of the cheatsheet (unlikely) but you get the idea.

PPS: If the output is too large you can create a function to append a textarea at the bottom of the page so that you can easily copy.

append = function(names){
ns = names.join('\n')
txtarea=document.createElement("textarea")
txtarea.innerHTML=ns
document.body.appendChild(txtarea)
}

and replace the last line in the first code with

append(names)

https://pastebin.com/JNtUcwyM - Complete list of complete class names with labels for version 5.0.1

if you retrieve a list of classes for a specific group you can add prefix and label then

var icons = []
brands.forEach(function(icon) {
      let element = {}
      element.className = "fab fa-" + icon;
      element.label = icon.replace(/-/g, ' ');
      icons.push(element);
});

console.log(JSON.stringify(icons))

Solution 17:^[17]

One-liner using bash:

curl https://raw.githubusercontent.com/FortAwesome/Font-Awesome/master/metadata/icons.json | jq 'keys'

In the format you want:

curl https://raw.githubusercontent.com/FortAwesome/Font-Awesome/master/metadata/icons.json | jq 'keys' | tr -d '\n' | sed 's/  "/"fa-/g'

Solution 18:^[18]

In latest font awesome 5.9 version we have around 1534 free icons, Divided into 3 categories

Solid icons
Regular icons
Brand icons

To use solid icons we need to add an additional class "fas" apart from Icon name

<i class="fas fa-address-book"></i>

Similarly to use Regular icons use "far" class name

<i class="far fa-address-book"></i>

To use brand icons use "fab"

<i class="fab fa-adobe"></i>

If you don't want to use default icon names by font awesome. You can use CSS content values to display icons as shown below

  .login::before {
  font-family: "Font Awesome 5 Free";
  font-weight: 900;
  content: "\f007";
}
<span class="icons login"></span> Login

I have listed down complete 1534 free icons along with their CSS content values in this article

Solution 19:^[19]

Alternative 1:

If you are using JS setup like all.js brands.js regular.js solid.js… ?

You can get the list from:

window.___FONT_AWESOME___

Tested in FontAwesome v5 and v6

Alternative 2:

Get raw data from their Metadata folder:

https://raw.githubusercontent.com/FortAwesome/Font-Awesome/master/metadata/icons.json

https://raw.githubusercontent.com/FortAwesome/Font-Awesome/master/metadata/icons.yml

Alternative 3:

Use their API ???

const query = `query allIcons {
    allIcons(
      version: "6.0.0-beta1"
      styles: ["solid"]
      page: 1
      perPage: 10000
      sort: "popularity"
    ) {
      iconCount
      icons {
        id
        label
        styles
        unicode
        membership { free pro }
      }
    }
  }
`
const data = fetch('https://api-canary.fontawesome.com', {
  method: 'POST',
  body: JSON.stringify( { query } ),
}).then(r => r.json()).then(({ data }) => {
  console.log(data)
})

Solution 20:^[20]

STEP 1: Goto this page, https://fontawesome.com/v5/cheatsheet/free/solid

STEP 2: Open developer console tab,

const dts = document.querySelectorAll('dd.icon-name')
const fas = [...dts].map(i => i.textContent)

You might have to adjust the script above, because the layout of the web page might change in the future.

Assemble

There's a lot of editor that can help you do multiple cursor operations. Ex. using Visual Studio Code, try ALT+Shift+Arrow to select rows so that you can append or delete to form new line of strings.
