The Patsy or Patsey Conroy Gang were a group of river pirates active along the New York waterfront of the old Fourth Ward during the post-American Civil War era. For nearly twenty years, the Patsy Conroys dominated the area of Corlears' Hook and were one of the last major waterfront gangs to remain in the district prior to the formation of the Steamboat Squad. The gang abruptly disappeared when their leaders Patsy Conroy, Larry Griffin and Denny Brady were imprisoned in 1874.
