The Galli-Curci Theatre is located on Main Street (state highway NY 30) in Margaretville, New York, United States. It is a brick building erected in the 1920s, now primarily used as a store, although some of the original theater remains. It was named after opera singer Amelita Galli-Curci, who summered at her historic country estate near Margaretville from 1922-1937 and sang at its opening night.
