The Triangle Inn–a former boarding house in the City of Venice, Florida–is the home to the Venice Museum. Operated by the City of Venice Division of Historical Resources, the museum serves as the city's history museum as well as the administrative offices for the division. Exhibit areas include an overall history of Venice; Dr. Fred Albee, famed surgeon and early land developer of Venice; the history of the Triangle Inn; prehistoric/natural history of Venice (Venice is known as the shark tooth capital of the world); and changing exhibits. The building was built in the Northern Italian Renaissance Revival style that was very popular in Florida in the 1920s. Key architectural features include stucco walls, clay tile roofs, triple arched windows, and a loggia.

The museum is open three days a week with additional weekend days during high season (October–April on the first and third Saturdays of the month from 11:00 a.m.–3:00 p.m.).

The building is listed on both the local and National Register of Historic Places.
