The DeLand House Museum is a historic house museum in DeLand, Florida. It features the DeLand House, which was once a part of the original property of Henry A. DeLand, the founding father of the city.

The DeLand House Museum is a historic structure owned and managed by the West Volusia Historical Society. The group acquired the property prior to 1990 when it was opened as a historic house museum. The site was preserved due to its association with Henry A. DeLand, who originally owned the lot that was later sold to the first attorney in DeLand, Arthur George Hamlin, who also built the house in 1886. The house is outfitted with period furnishings that are mostly donated by locals.
