Devoy Barracks (Irish: Dún Uí Dhubhuí) was a military installation in Naas, County Kildare in Ireland.

[1] In 1873 a system of recruiting areas based on counties was instituted under the Cardwell Reforms and the barracks became the depot for the 102nd Regiment of Foot (Royal Madras Fusiliers) and the 103rd Regiment of Foot (Royal Bombay Fusiliers).

[2] Following the Childers Reforms, the 102nd and 103rd regiments amalgamated to form the Royal Dublin Fusiliers with its depot in the barracks in 1881.

[3] The barracks were secured by the forces of the Irish Free State in February 1922.

[1] The Irish Army Apprentice School was established on the site in 1956 but closed in 1998 when the barracks were finally decommissioned.
