Foras na Gaeilge (, "Irish forum"; often abbreviated to FnaG) is a public body responsible for the promotion of the Irish language throughout the island of Ireland. It was set up on 2 December 1999, assuming the roles of Bord na Gaeilge, An Gúm, and An Coiste Téarmaíochta, which had formerly been state bodies of the Irish government.
The body is an agency of The North/South Language Body, which was formed as a cross-border implementation body under the terms of the Good Friday Agreement to oversee the furtherance of the native languages of the island of Ireland. Foras na Gaeilge promotes Irish, and its counterpart Tha Boord o Ulstèr-Scotch promotes Ulster Scots.
The body also serves an advisory role in matters pertaining to the Irish language in both the public and private sectors in the Republic of Ireland (where Irish is the first official language) and Northern Ireland (where Irish is a regional language). The largest series of events core-funded by Foras na Gaeilge is Seachtain na Gaeilge (English: Irish (language) week), in the run up to St Patrick's Day with events held throughout the world.
Foras na Gaeilge also creates terminology to add to the Irish language.
