The Beacon Theatre, was an American Art Deco performing arts theatre located in Beacon, New York, in the Hudson Valley on Main Street in the city's downtown section (known as "Theatre Square"), across from the Fishkill Creek. The theatre was run by 4th Wall Productions, which has been producing live theatre in the Hudson Valley since 1994, from 2010 until they sold the building in 2015. The main stage was gutted and converted into residential units, with the second floor converted into a smaller performance space.
