The Kandiyohi County Historical Society (KCHS) is a local history museum in Willmar, Minnesota, United States.

The archives and Lawson research library are the principal sources used by KCHS staff, volunteers, and visitors to carry out this mission today and into the future.

[1] KCHS consists of six buildings: a main museum and research library; the Sperry House, a restored turn-of-the-century Victorian home; a one-room schoolhouse; an agricultural barn; a restored log cabin which was a site of the 1862 US-Dakota conflict;[1] and Great Northern Passenger Engine #2523.
