Moosomin-Montmartre is a provincial electoral district for the Legislative Assembly of Saskatchewan, Canada.

Formerly represented by speaker Don Toth, it is arguably one of the most conservative ridings in the province, having been in the hands of a centre-right party without interruption since 1975.

The largest centre in the constituency is the town of Moosomin.

Other towns in the district include Grenfell, Kipling, Montmartre, Broadview, Whitewood, Rocanville and Wolseley.

The riding was renamed Moosomin-Montmartre for the 2024 general election.
