The Prison Ship Martyrs' Monument is a war memorial at Fort Greene Park, in the New York City borough of Brooklyn. It commemorates more than 11,500 American prisoners of war who died in captivity aboard sixteen British prison ships during the American Revolutionary War. The remains of a small fraction of those who died on the ships are interred in a crypt beneath its base. The ships included HMS Jersey, Scorpion, Hope, Falmouth, Stromboli, Hunter, and others.
