USS O'Brien (DD-415) was a World War II-era Sims-class destroyer in the service of the United States Navy, named in honor of Captain Jeremiah O'Brien and his five brothers, Gideon, John, William, Dennis and Joseph, who captured HMS Margaretta on 12 June 1775 during the American Revolution.

O’Brien was laid down at Boston Navy Yard, Boston, Massachusetts, on 31 May 1938; launched on 20 October 1939; sponsored by Miss Josephine O’Brien Campbell, a great-great-great granddaughter of Gideon O’Brien; and commissioned on 2 March 1940. Since this warship was built in a drydock, along with the destroyers Walke, Lansdale, and Madison, the christening and commissioning ceremonies were combined.
