Castlebar Barracks (Irish: Dún Chaisleán an Bharraigh) was a military installation at Rock Square in Castlebar, County Mayo in Ireland.

The infantry barracks at Castlebar, which were built on the site of an old castle, were completed in 1834. The barracks became the home of the 3rd Battalion, the Connaught Rangers in the late 19th century and it was at Castlebar that the battalion was disbanded in 1901. A part of barracks was burnt down by the Irish Republican Army in spring 1922 before the site was secured by the forces of the Irish Free State in summer 1922. The barracks were subsequently renamed Mitchel Barracks after John Mitchel, an activist for Irish nationalism. The barracks, which latterly were being used as a training camp by the Reserve Defence Forces, closed in March 2012 and the site has since been acquired by the local council.
