Constructed in 1855 of native limestone, the Custer House is a historic house museum located on Fort Riley in Kansas, United States.

It reflects Fort Riley's earliest history and authentically depicts military home life on the western frontier during the Indian Wars Period.

It is largely unchanged from its original design and furnished with period furniture from the 1880 through the 1890s.

Custer House is also available, upon request, by coordinating with the nearby Fort Riley Cavalry Museum.

Since the museum is on an active U.S. Army post, there are minor restrictions on visitors, namely a requirement for state or federally issued photo identification (i.e. a driver's license).
