The Mount Stephen Club was a private members' club in Montreal, Quebec. It was founded in 1926 as a gentlemen's club for businessmen by mining magnate Noah Timmins, J.H. Maher and J.S. Dohan.

The clubhouse was located on Drummond Street at George Stephen House, which had been built in 1883 as a family home for Lord Mount Stephen. The club took its name from the mansion's first owner, and it was considered to be a lair of the wealthy community of Anglophone Montrealers.

Starting in 1964, women visiting the club were allowed to come in by the same entrance as men, but only on Thursdays. During the mid-1970s, women became equal members of the club, which continued until it closed in 2011.

Various well-known people visited the club over the years, including Princess Margaret, Countess of Snowdon, Princess Benedikte of Denmark, John Diefenbaker, Pierre Trudeau, Brian Mulroney, Percival Molson, Lucien Bouchard, Louise Harel and Edgar Bronfman.
