Volunteer was an American racing yacht built in 1887 for the America's Cup races. It was the victorious American defender of the seventh America's Cup match that same year against Scottish challenger Thistle.
Volunteer easily beat the 1886 America's Cup defender Mayflower during the defender trials for the 1887 America's Cup and won both Cup races on September 27 and 30, 1887, against Thistle. Volunteer was skippered by Captain Hank Haff with the assistance of Captains Terry, Berry and L. Jeffreys.
Soon after the Cup races, Volunteer was bought by John Malcolm Forbes (who also owned Puritan) and was altered as a schooner in 1891. It was broken up at a New York junkyard in 1910.
