Slocum House, Victorian mansion in Vancouver, United States

The Slocum House is a two-story Carpenter Victorian at the southwest corner of Esther Short Park in Vancouver, Washington. Its vertical Italianate lines and ornamental details are attributed to Edward Slocum, brother of owner Charles W. Slocum. Inside, ornamental medallions carry patent dates of 1842 and 1846.

Charles W. Slocum, a carpenter trained in Rhode Island who became superintendent of the Vancouver Barracks, laid the foundation in May 1877 and finished the house by early 1878. The 1867 date often cited is unsupported by local newspapers, which record no dwelling on the land that year. The house was sold in 1929 to the family of Frederick Leadbetter and served as an office for the Columbia River Paper Company until the 1960s.

Since 1966 the house has served as a community theatre; Hermine Decker of the Old Slocum House Theatre Company insisted all plays be 19th century to complement the building. Its 60-seat stage hosted 11 plays before the house met city fire and safety codes in August 1974.

The house stands near downtown Vancouver and can be viewed from the outside, with the best views from the park side. The nearby pathways around the park are freely accessible and offer a good vantage point of the building.

The building narrowly escaped demolition in 1965 thanks to community efforts that led to its relocation one block away. This rescue operation was one of the region's early successes in historic preservation.
