The Prince of Wales's Leinster Regiment (Royal Canadians) was an infantry regiment of the line in the British Army, formed in 1881 by the amalgamation of the 100th (Prince of Wales's Royal Canadian) Regiment of Foot and the 109th Regiment of Foot (Bombay Infantry). The 100th Foot was first raised in 1763 and the 109th was first raised in 1761. Between the time of its formation and Irish independence, it was one of eight Irish regiments raised largely in Ireland, its home depot in Birr. It was disbanded with the Partition of Ireland following establishment of the independent Irish Free State in 1922 when the five regiments that had their traditional recruiting grounds in the counties of the new state were disbanded.
