The Portland Museum is a neighborhood history and art museum in Louisville, Kentucky. It details the history of the Portland neighborhood both as an independent town in the early 1800s and after Portland's amalgamation into Louisville after the construction of the Portland Canal. The museum consists of three buildings: Beech Grove, a 19th-century Italianate mansion, the former Portland Bridge Baptist Mission Building, connected at Beech Grove's north side, and the AHOY House, a renovated Victorian property adjacent to the museum.
