The Vail-Leavitt Music Hall is a late nineteenth-century theater presently in use on the east end of Long island in Riverhead, New York.

In 1908, George M. Vail, now sole owner of Music Hall, sold the building to Simon Leavitt, a tailor and clothier, who leased out the upstairs as a theatrical venue.

In 1914, the Music Hall was used by Thomas Edison as a demonstration site for kinetophone, an early attempt at the synchronization of sound and film.

As more modern theaters were built in the area, the Music Hall was converted for use over the years as a restaurant, a roller skating rink and even a betting parlor.

From the early eighties to the late nineties, old movies were shown on a small screen in its downstairs space, dubbed the "Mini-Cine".
