Rosthern-Shellbrook is a provincial electoral district for the Legislative Assembly of Saskatchewan, Canada. The riding was last contested in the 2020 election, when incumbent Saskatchewan Party MLA and Premier Scott Moe was re-elected.
Communities in the district include the towns of Rosthern, Shellbrook, Hafford, Blaine Lake, and Spiritwood; and the villages of Canwood, Laird, Medstead, Leask, and Shell Lake.
The constituency was created in 2002 from portions of Shellbrook-Spiritwood, Redberry Lake, and Rosthern, and was first contested in the 2003 general election. Rosthern-Shellbrook will gain significant territory from Biggar-Sask Valley for the next general election, in what will be the riding's first major boundary reconfiguration since its creation.
