Osler is a town in the Canadian province of Saskatchewan, founded in the 1890s. The community was named after Sir Edmund Boyd Osler (1845–1924), who was an Ontario-based explorer, railroad financier, and Member of Parliament.
The town has a library, seniors' centre, volunteer fire department, gas station, grocery store, first responders, leisure centre, two schools, and four churches. Osler is about 20 km north of Saskatoon.
