Chamberlain is a village in the Canadian province of Saskatchewan within the Rural Municipality of Sarnia No. 221 and Census Division No. 6. Chamberlain is notable for being the last community between Regina and Saskatoon that Highway 11, the Louis Riel Trail, still passes through. The highway narrows to two lanes and its speed limit is reduced from 110 km/h to 50 km/h. A number of small restaurants and gas stations benefit from having traffic pass through at slow speed.
