The Mount Royal Arena () was an indoor arena located in Montreal, Quebec, Canada at the corner of Mount Royal and St. Urbain Street. It was home of the National Hockey League (NHL) Montreal Canadiens from 1920 to 1926, before moving to the then two-year-old Montreal Forum. It had a capacity of 6,000 seated, 10,000 when including standing room. It was a natural ice rink, without machines to freeze the ice mechanically.
It opened, partly unfinished, on January 10, 1920, for a game between the Canadiens and Toronto, won by Montreal 14–7. A week later, parts of a balcony broke before a game with Ottawa, and police stopped sales at 6,500. On February 29, 2000, it was destroyed by fire.
