Selkirk is a city in the western Canadian province of Manitoba, located about 22 kilometres (14 mi) northeast of the provincial capital Winnipeg on the Red River. It has a population of 10,278 as of the 2016 census.

The mainstays of the local economy are tourism, a steel mill, and a major psychiatric hospital. A vertical lift bridge over the Red River connects Selkirk with the smaller town of East Selkirk. The city is connected to Winnipeg via Highway 9 and is served by the Canadian Pacific Railway.

The city was named in honour of Scotsman Thomas Douglas, 5th Earl of Selkirk, who obtained the grant to first establish a colony in the Red River area in 1813.

The present-day city is near the center of the 160,000 square mile (530,000 km2) area purchased by the Earl of Selkirk from the Hudson's Bay Company. The first settlers of the Red River Colony arrived in 1813.

Although the settlers negotiated a treaty with the Salteaux Indians of the area, the commercial rivalry between the Hudson's Bay Company and the North West Company gave rise to violent confrontations between the settlers and the trading companies. In recognition of the Earl's importance in bringing settlers to the region, the town was named Selkirk and incorporated in 1882.
