Come Out, Ye Black and Tans is an Irish rebel song referring to the Black and Tans, who were "special reserve constables" (mainly former World War I army soldiers), recruited in Great Britain and sent to Ireland from 1920, to reinforce the Royal Irish Constabulary (RIC) during the Irish War of Independence. The song was written by Dominic Behan as a tribute to his Irish Republican Army (IRA) father Stephen, who had fought in the War of Independence, and is concerned with political divisions in working-class Dublin of the 1920s. The song uses the term "Black and Tans" in the pejorative sense against people living in Dublin, both Catholic and Protestant, who were pro-British.

The melody of the song was adapted by Behan from an old air, Rosc Catha na Mumhan (Irish for "Battlecry of Munster"), by Piaras Mac Gearailt (Pierce FitzGerald, c. 1709 – c. 1792), which is also ironically used by the loyalist song, The Boyne Water.
