109th Regiment of Foot (Bombay Infantry)

The 109th Regiment of Foot (Bombay Infantry) was an infantry regiment of the British Army from 1862 to 1881, when it was amalgamated into The Prince of Wales's Leinster Regiment (Royal Canadians).

The regiment was originally raised by the Honourable East India Company in 1853 as the 3rd Bombay (European) Regiment, and served in the Indian Mutiny of 1857. As with all other "European" units of the Company, they were placed under the command of the Crown in 1858, and formally moved into the British Army in 1862, ranked as the 109th Foot.

As part of the Childers Reforms in 1881, the regiment was amalgamated with the 100th (Prince of Wales's Royal Canadian) Regiment of Foot to form The Prince of Wales's Leinster Regiment (Royal Canadians).
