Arnold L. Schuster (February 21, 1928 – March 8, 1952) was an American clothing salesman and amateur detective known for his involvement in the capture of bank robber Willie "The Actor" Sutton and for Schuster's subsequent murder by either the Gambino crime family, associates of Sutton, or any one of the many suspects police questioned about his death. He was a distant paternal cousin of literary agent and book publisher M. Lincoln ("Max") Schuster of Simon & Schuster.
