Yamaska (French pronunciation: [jamaska]) was a provincial electoral district in the Montérégie region of Quebec, Canada.

It was created for the 1867 election (and an electoral district of that name existed earlier in the Legislative Assembly of the Province of Canada and the Legislative Assembly of Lower Canada). Its final election was in 1970. It disappeared in the 1973 election and its successor electoral district was Nicolet-Yamaska.
