Founded in 1910, St. Denis is a community in Saskatchewan with an estimated population of 30 in the village itself and nearing 100 with the surrounding farms.
A post office was established at St. Denis in 1909 but it closed in 1911. Leon Denis was postmaster. The post office was located on the Leon Denis homestead at NE 24-37-R1 w 3rd meridian.
St. Denis maintains close cultural ties with the nearby communities of Prud'homme and Vonda. The three communities were originally settled by French speaking settlers in the early 1900s.
