Blair of the Mounties is a syndicated 15-minute radio series chronicling the adventures of Sergeant James Blair of the North-West Mounted Police. Over the course of the 39-episode series, which aired for over twenty years on radio stations in the United States, Canada, and Australia, Blair serves in various Canadian locations with the assistance of Corporal Marshal, played by Jack Abbott. The show was written by Colonel Rhys Davies, who also portrayed Blair and based the series on his own experiences as a Canadian Mountie.

Known for its minimal sound effects, the show has been described as both amateurish and fascinating, with Blair sometimes coming off as a bit stuffy. The series originally aired in 1938, though it may have been on air as early as 1935. It is believed to have inspired the Challenge of the Yukon radio series.
