Owen Sound (Canada 2011 Census population 21,688; CA population 32,092), the county seat of Grey County, is a city in Southern (Southwestern) Ontario, Canada. Owen Sound is located at the mouths of the Pottawatomi and Sydenham Rivers on an inlet of Georgian Bay.
The area around the upper Great Lakes has been home to the Ojibwe people since prehistory. In 1815, William Fitzwilliam Owen surveyed the area and named the inlet after his older brother Admiral Edward Owen. A settlement called Sydenham was established in 1841 by Charles Rankin. The settlement was renamed in 1851 and became an incorporated town in 1857.
