A cruise ship or cruise liner is a passenger ship used for pleasure voyages, where the voyage itself and the ship's amenities are a part of the experience, as well as the different destinations along the way, i.e., ports of call.

Transportation is not the only purpose of cruising, particularly on cruises that return passengers to their originating port (also known as a closed-loop cruise), with the ports of call usually in a specified region of a continent. There are even "cruises to nowhere" or "nowhere voyages" where the ship makes 2–3 night round trips without any ports of call.
