Patrick L. Hearne, also spelled Hern, Hearn or Herne, (died July 4, 1859) was an American gambler, sportsman and underworld figure in New York City during the mid-19th century. He was the first man, along with fellow gambler Henry Colton, to open "first-class" casinos in the city during the 1830s. His self-named resort in lower Broadway was especially popular in the years prior to the American Civil War and regarded in the city as "perhaps the most famous gambler of the era".
