The Downtown Ossining Historic District is located at the central crossroads of Ossining, New York, United States, and the village's traditional business district known as the Crescent. Among its many late 19th- and early 20th-century commercial buildings are many of the village's major landmarks—three bank buildings, four churches, its village hall, former post office and high school. It was recognized as a historic district in 1989 and listed on the National Register of Historic Places, as one of the few downtowns in Westchester County with its social and historical development intact.
