'''TG4''' ({{IPAc-en|ˌ|t|i:|_|dʒ|i:|_|ˈ|k|æ|h|ər}}; {{langx|ga|TG Ceathair}}, {{IPA|ga|ˌtʲeːɟeː ˈcahəɾʲ|pron}}) is an Irish [[free-to-air]] public service television channel. It launched on 31 October 1996 and is available online and through its on-demand service [[TG4 Player]] in Ireland and beyond.

TG4 was initially known as '''{{lang|ga|Teilifís na Gaeilge|italics=no}} (TnaG)''', before being renamed in 1999. TG4 was the third national station to be launched in Ireland, after [[RTÉ One]] in 1961 (as {{lang|ga|Teilifís Éireann}}) and [[RTÉ Two]] in 1978. It was followed by a fourth channel, TV3 (now called [[Virgin Media One]]), in 1998.

On average 1.2m people watch TG4 in the Republic of Ireland every week.<ref>{{Cite web |title=About TG4 {{!}} Irish Language Television, Online Streaming Player |url=https://www.tg4.ie/en/corporate/background/ |access-date=2024-01-10 |website=TG4 |language=en-ie}}</ref> 650,000 viewers tune into the channel each day.
