Ambroise-Dydime Lépine (18 March 1840 – 8 June 1923) was a military leader of the Métis under the command of Louis Riel during the Red River Rebellion of 1869-1870. He was tried and sentenced to death for his role in the rebellion and for the execution of Thomas Scott, but his sentence was commuted by Governor General Lord Dufferin. He is buried in the churchyard of the St. Boniface Cathedral next to Louis Riel.
