Saint Martin is an impact structure in Manitoba, Canada. It is located in the northern part of the Rural Municipality of Grahamdale, northwest of Lake St. Martin.
The impact structure is 40 km (25 mi) in diameter and its age was determined to be 227.8 ± 1.1 million years (Carnian stage of the Triassic) using the argon-argon dating technique. The crater is well preserved but poorly exposed at the surface as the whole region is covered by glacial drift.
