The Lyceum Theatre was in Boston, Massachusetts, located at 661–667 Washington Street, at the corner with Boylston Street. It opened as the Boylston Museum in 1875 at 667 Washington Street. It operated as both a theatre and a dime museum. Its founder, George E. Lothrop, acquired the adjacent properties and greatly expanded the theatre. This expanded facility opened as the World's Museum in 1885. In 1892, the theatre ceased to be a dime museum and was renamed the Lyceum Theatre after undergoing significant alterations. It was demolished in June 1908. The Gaiety Theatre was built on the same site in 1908.
