The Brooklyn Theatre Fire was a catastrophic theatre fire that broke out on the evening of December 5, 1876, in the then-city of Brooklyn, now a borough of New York City, New York, United States. The conflagration killed at least 278 individuals, with some accounts reporting more than 300 dead. One hundred and three unidentified victims were interred in a common grave at Green-Wood Cemetery. An obelisk near the main entrance at Fifth Avenue and 25th Street marks the burial site. More than two dozen identified victims were interred individually in separate sections at the Cemetery of the Evergreens in Brooklyn.
