The Actaea, or Actea, was a 19th-century Boston yacht built in 1880 by Weld and David Clark of Kennebunk, Maine for David Sears, Jr., of Montgomery Sears of Boston. She was purchased by a group of New York Sandy Hook Pilots in 1890. She was one of the largest and fastest pilot boats in the fleet. In the age of steam, the Actaea was sold in 1896 to John J. Phelps of the New York Yacht Club and used as a pleasure yacht.
