Britain's Joe Salisbury and America's Rajeev Ram edged a close final to become the first pair this century to retain the US Open men's doubles title.
They won 7-6 (7-4) 7-5 against Salisbury's compatriot Neal Skupski and Dutchman Wesley Koolhof.
Australian duo Mark Woodforde and Todd Woodbridge were the last pair to win successive New York titles in 1995-96.
Salisbury donned a black armband and Skupski wore a black ribbon during the final in tribute to Queen Elizabeth II.
