The Official Languages Act 2003 (Irish: Acht na dTeangacha Oifigiúla 2003) is an Act of the Oireachtas of Ireland. The Act sets out rules regarding use of the Irish language by public bodies; established the office of An Coimisinéir Teanga to monitor and enforce compliance by public bodies with the provisions of the Official Languages Act; and made provision for the designation of official Irish-language versions of placenames and the removal of the official status of English placenames in the Gaeltacht. The Act is being implemented on a phased basis.
