The Prospect House is a historic building located at 11 Hammond Street in Waltham, Massachusetts.
Built in 1839, this temple-front Greek Revival structure was originally a hotel and tavern, and is one of only a few surviving 19th century hotel buildings in the city.
Now an apartment house, the building has four two-story fluted Doric columns supporting a pedimented gable, with a second-story porch behind the columns.
Early pedimented dormers have been linked together in later alterations.

The building was listed on the National Register of Historic Places in 1989.
