Walker is a city in Cass County, Minnesota, United States.

The area was inhabited for thousands of years by succeeding cultures of indigenous peoples.

Before European settlement, the Ojibwe moved into the area from the Great Lakes, pushing out the historic Dakota peoples, such as the Assiniboine and Hidatsa.

Following the construction of the railroad to the area, Patrick McGarry founded Walker in 1896.

He named the settlement after the logging giant Thomas B. Walker, in hopes of luring construction of a sawmill.

Walker developed with business, jobs and other services generated by four other logging companies.

In 1907, Walker became the home of the Ah-Gwah-Ching Center, first constructed as a residential facility for tuberculosis (TB) patients, who at the time could be treated only with good nutrition and rest.

The facility had its own farm and dairy herd, the patients and staff put on skits and produced a newspaper, and it had its own railroad depot at one time.

According to the United States Census Bureau, the city has an area of 2.47 square miles (6.40 km2), all land.
