The Irish language has 3 dialects:
The main dialect of Irish taught in schools, used in media and for official purposes is the Caighdeán Oifigiúil or 'Standard Irish', a standardised form of the language largely based on the Connacht dialect (due to the Connacht Gaeltacht having the largest number of native speakers). Most of the resources here use the Standardised form, though there are also resources for learning the dialects.
There are Gaeltachta (Irish-speaking areas) in all 4 provinces of Ireland. The Gaeltacht Bill that passed in 2012 could mean that areas such as Ennis and Clondalkin could gain the status of Líonra Gaeilge (areas with strong Irish-speaking communities) over the next few years.
Also, bear in mind that while the Irish name for the language is Gaeilge, in English we refer to it as 'Irish', not 'Gaelic'. Gaelic is a language group (comprising of Irish, Scottish Gaelic and Manx), and if you refer to Irish as 'Gaelic', you'll sound like an American tourist.
Gaeilge Outside Ireland
There is a Permanant North American Gaeltacht in Canada (their offical website is here), so Murricans and Canadians can go up there and learn Irish if they want (it's probably a lot cheaper than coming to Ireland for practise). Apparently, there was also a Newfoundland dialect of Irish up until pretty recently.
Gaeilge San Astráil has tons of info on Irish in Australia, and includes a fortnightly magazine called An Luibín, which is available for download.
Coláiste na nGael has a lot of links to learning resources, classes etc. in Britain.
- Buntús Cainte This series of books is everywhere, you can get it in pretty much any bookshop with an Irish section. Comes with a CD, so you can hear everything being pronounced. Probably the best place to start
- Irish Learning Pack Torrent with tons of learning material in it, including several of the books I've mentioned here
- Teach Yourself Irish (Myles Dillon & Donnacha Ó Cróinín, 1961) I've heard this book highly recommended for those who want to learn Munster Irish (specifically Cork Irish). The spellings are a little different to the modern Caighdeán, but not as different as before the spelling reforms.
- Leabhar Gramadaí Gaeilge/ Irish Grammar Book by Nollaig Mac Congail This is the best and clearest book available on Irish grammar (we used it in university). Link is to the English-language version, but there's one in Irish too. For beginners, it might be a better idea to get the English one first

- Intermediate Irish: A Grammar and Workbook

Meetups and Conversational Groups
- Most universities in Ireland have Irish-language societies, e.g. Trinity, UCC, UCD, NUIG, Queens, etc. There's probably loads more (some universities have 2 or more), so have a look yourself.
- Club Conradh na Gaeilge This is a pub underneath Conradh na Gaeilge on Harcourt St. in Dublin. Cheap pints, so worth a visit for that anyway.
- ReRá These guys hold a conversational group in the Franciscan Well in Cork every so often. Seems to be primarily a chat while having a few drinks, but they do competitions and stuff too. I'll update this when I know more about them.
- Na Gaeil Óga CLG An Irish-speaking GAA club founded in Dublin a few years ago.
Radio Stations [All of these can be listened to online, look for a button saying Éist ('listen') or Éist Linn ('listen to us')]
- Raidió na Gaeltachta (aka RnaG) This is the main Irish-language radio station. Lots of traditional music and conversation. It's often a bit dull, but it's the best-quality Irish you'll hear anywhere, with plenty of native speakers, and a variety of dialects. 93-95 FM (I think), also online, and can be listened to on Sky channel 0166.
- Raidió Na Life (Liffey Radio) A long-running station based in Dublin. It's a bit more accessible than RnaG (albeit with non-Gaeltacht speakers), and plays some good music. Tends to have a lot more Urban Irish than RnaG. You can listen to it online, and they also have podcasts. 106.4 FM and online.
- Raidió Fáilte This is a station based in Belfast. It's pretty good, they play some great tunes. Being in the North, they speak in the Ulster dialect (or, at least, standard Irish with an Ulster flavour), which is a little different from Munster and Connacht dialects; it's great for getting used to hearing that accent. 107.1 FM and online.
- Raidió Rí-Rá A radio station aimed at younger people. They tend to play a lot of top-40 music, so there's less conversation, but worth a listen anyway. They don't broadcast on FM anymore, but you can listen online.
- TG4 (Pronounced "tee-gee-ceathair") This is Ireland's Irish-language TV station. They're producing some good stuff lately (especially good travel programs, for some reason), so its well worth a watch. They usually put English subtitles on their shows as well.
- BBC have a surprising number of Irish programs, so it's worth keeping an eye out for them.

- How To Swear in Irish Clár teaches you how to say bad words in Irish

Software & Games

- Abair This is an interesting one- it's a text-to-speech project from TCD where you type in words or phrases, and it plays them back to you in a dialect of your choice. Currently they have the Gaoth Dobhair and Connemara dialects, and they say they're going to include a Munster dialect soon.
- Site with Irish versions of software Includes Bittorrent, Utorrent, Firefox, and a few others. If the software has a Gaeilge setting, it highlights it.
- Irish is available as a language option for Facebook. I highly recommend using it, it's a brilliant way to keep up your Irish on a regular basis
- For those using Windows 8, Irish is a display option. As with Facebook, it's incredibly useful, as it means you're seeing Irish constantly. You get used to it straight away, so it's a pretty much zero-effort way to keep up your Irish. Same for other software with Irish settings
- Google in Irish You can set the language option so it's permenantly through Irish
- Wordpress in Irish Can be downloaded from this link
- Cléclic A site with downloadable video games in Irish
- Site with Irish versions of software Includes Bittorrent, Utorrent, Firefox, and a few others. If the software has a Gaeilge setting, it highlights it.

- Gaelchló Interesting site where you can download font sets of old Irish Script (the kind that was used before the 20th Century spelling reforms) for use on your computer
- Skype as Gaeilge A project to create an unofficial Irish setting for Skype. It's not complete yet, but watch this space (It's at 85% atm. Weirdly, the one for Scots Gaelic is at 100%) [Note: If you put Windows 8 through Irish, it automatically puts Skype in Irish as well]
- Flann O'Brien/ Myles na gCopaleen/ Brian O'Nolan Very famous writer in both English and Irish. His works tend to be either satirical or surreal, and usually pretty funny. He spoke Irish fluently, and wrote An Béal Bocht as a parody of the genre of novels typified by 'Peig' (Peig Sayers) and 'An tOileánach' (Tomás Ó Criothain). It's not too difficult, but if you read it side-by-side with the English version you'll get more of the jokes.
- Peadar Ua Laoighaire A celebrated writer from Cork who wrote around the beginning of the 20th Century. He argued, before an Caighdeán Oifigiúil was introduced, that Munster Irish should become the standard, and wrote books like Séadna as examples of what he considered to be good Irish.
- Ruaidhrí Ó Báille- wrote Dúnmharú ar an Dart, a book used a lot in schools. It's reasonably easy Irish, so great for people who are just learning. T-Rex Ó Saurus rapping about it
- Mairtín Ó Cadháin One of the most famous writers in Irish of the 20th Century. He wrote in a modernist style, and was a professor of Irish at Trinity at one point.
- Alan Titley One of the more well-known writers out there atm. He's written a good number of books and plays, and writes regularly in the Billeog section of the Irish Times. He's also a bit of a legend irl.
- Seán Ó Ríordáin Probably the greatest poet in Irish of the 20th Century. He was from Baile Bhúirne (in the Muskerry Gaeltacht) in Cork. He was responsible for bringing modern European elements to Irish poetry, and really evolved it. No list of Gaeilge authors is complete without him. Eireaball Spideoge and Tar Éis Mo Bháis are probably his most famous works.
- Maidhc Dainín Ó Sé The late father of Daithí Ó Sé, Maidhc Dainín was a well-loved figure from the Kerry gaeltacht, and is considered to be one of the best ever proponents of the Irish language. He wrote fairly extensively, so his books are worth a look.
- Gaelport This is a big list of classes (irl and online) all over the place, both in Ireland and in other countries (England, Canada, Australia, etc)
- GaelChultúr These guys do classes in various places around the country, including Dublin. Apparently they do classes for every level, and have been awarded third-level status.

- Oideas Gael Adult courses up in the Gaeltacht in Donegal
- Oidhreacht Chorca Dhaoine They offer courses in Corca Dhaoine in Kerry
- Canadian Gaeltacht These guys allegedly run courses up in the Canadian Gaeltacht, but their site hasn't been updated in ages (this might be just because they're not very good with computers). I'd say ring them up and ask, it'd be a handy resource for those wanting to learn it in North America

- Gael Linn An Irish language organisation that run Adult courses and have various other resources
- Foras na Gaeilge An organisation for promoting Irish. They run classes as well apparently

- Vicipéid Wikipedia in Irish
- Doegen Records Web Project Really interesting site- it's a digital archive of a ton of recordings made at the start of the 20th century of various dialects, including now-extinct ones such as Armagh, Tipperary and Tyrone Irish. Click on your county on the map, and it'll show you all the recordings it has; you can stream the recordings (and download the mp3s if you like), and there's both transcriptions of the recordings and translations of them on each page. What better way to get (back) into learning the language than by learning then native dialect of your area?
- RTÉ Ríleanna agus Téipeanna More dialect recordings- this series has a number of recordings from around the country, including the Clare Gaeltacht, which wasn't recognised for political reasons, and which people are now currently trying to revive. Download them before RTÉ randomly take down the page!
