A pirate ship is a type of amusement ride consisting of an open, seated gondola (usually in the style of a pirate ship) which swings back and forth, subjecting the rider to various levels of angular momentum. A variant where the riders must pull on ropes to swing the ride is known as a swing boat.

Height requirements for this type of ride vary from park to park. For example, Hersheypark, which has a Huss Pirate Boat, has a height requirement of 42 in (107 cm) or more to ride, while at LaRonde, which also has a Huss Pirate Boat, riders must be 52 in (132 cm) or taller. Huss recommends that the lowest a height requirement should be is 39 in (99 cm), but parks can make it higher if they choose to.

There are a number of Swinging Ship-type rides, and multiple manufacturers.

The names listed are given by the manufacturers, and individual parks may change the name of the ride itself. Many parks use a Viking Ship theme for their ride. Smaller versions of the ride are often called "Swingboats".
