A windjammer is a commercial sailing ship with multiple masts that may be square rigged, or fore-and-aft rigged, or a combination of the two. The informal term "windjammer" arose during the transition from the Age of Sail to the Age of Steam during the 19th century. The Oxford English Dictionary records the word "windjamming" from 1886 and "windjammer" with reference to a ship from 1892. The term has evolved to include such a vessel, carrying passengers on overnight cruises in the Caribbean, the U.S. state of Maine and elsewhere.

A sailing ship is a sea-going vessel that uses sails mounted on masts to harness the power of wind and propel the vessel. There is a variety of sail plans that propel sailing ships, employing square-rigged or fore-and-aft sails. Some ships carry square sails on each mast—the brig and full-rigged ship, said to be "ship-rigged" when there are three or more masts. Others carry only fore-and-aft sails on each mast, for instance some schooners. Still others employ a combination of square and fore-and-aft sails, including the barque, barquentine, and brigantine.
