An Coiste Téarmaíochta is the Terminology Committee of Foras na Gaeilge.
It chooses terminology for words and new concepts in the Irish language.
It was founded in 1968 and was initially a division of the Department of Education.
Under the Good Friday Agreement Foras na Gaeilge was founded in 1999 and was charged with the development of new terminology in Irish.
An Coiste Téarmaíochta has been operating as part of the Foras since then.
