Weyburn-Bengough is a provincial electoral district for the Legislative Assembly of Saskatchewan, Canada.

Located in southeastern Saskatchewan, the constituency was created as Weyburn-Big Muddy for the 1995 general election by combining parts of Weyburn and Bengough-Milestone.

Smaller communities in the district include the towns of Willow Bunch, Coronach, Ogema and Bengough; and the villages of Minton, Pangman and Mctaggart.

For the 2024 general election, the riding was renamed Weyburn-Bengough and shifted to the north, gaining significant territory from Indian Head-Milestone, Lumsden-Morse and Moosomin and losing territory to Estevan-Big Muddy and Cannington.
