St. Boswells is a hamlet in Glen Bain Rural Municipality No.

Very little remains of the former village except a well known as the best water around, and sidewalks which mark the once prosperous business section of St. Boswells.

St. Boswells was a railroad town founded in 1918, as a Canadian National Railway point along the line from Moose Jaw to Neidpath, though the surrounding area had been settled at least a decade earlier.

Named after Alex Dow's, hometown of St. Boswells, Roxburghshire, Scotland.

St. Boswells was chosen as the name for the community's first post office.
