The Irish Bookbinders' and Allied Trades Union (Irish: Cumann Ceirde Cluduigte Leabar Agus a Com-Ceard i n-Eirinn) was a trade union representing print workers in Ireland. The union was founded in 1920 as the Irish Bookbinders' and Paper Rulers' Trade Union, by Dublin-based members of the UK-based National Union of Bookbinders and Machine Rulers. It became the "Irish Bookbinders' and Allied Trades Union" in 1938. From 1941, the Irish government required unions to obtain a license, and the National Union thereafter withdrew from Ireland, the Irish Bookbinders thereafter recruiting throughout the country; by the 1950, it had around 1,000 members.
