The primary mission of the Lacey Museum is to collect, interpret, and display historical materials that illustrate the history of the Lacey area in all periods of its development. In a changing community, the Lacey Museums works to preserve and interpret Lacey history and identity. Through exhibits, educational programs, and research archives, the museum tells the story of Lacey's past, present, and future.

The Lacey Museum is located in an historic structure originally built in 1926 by Fred Russell as a private residence. In the late 1940s the building was used by the Lacey Volunteer Fire Department, and was later used as city hall when Lacey was incorporated as a city in 1966. City government outgrew the facility, and by 1979 the decision was made to create a local museum on land donated by Lacey Women's Club. The building was moved, and in 1981 the Lacey Museum opened to the public.
