The USS Swinetrek is the spaceship in the Pigs in Space sketches on The Muppet Show. The Swinetrek’s crew includes Captain Link Hogthrob, the indomitable First Mate Piggy (played by Miss Piggy), the inscrutable Dr. Julius Strangepork and twenty-two other pig crew members. Several missions have required the ship to land on the planet Koozebane.
The exterior of the ship is porcine in appearance. The ship's interior, as displayed on screen, is limited to the bridge area, which includes three chairs for the crew, a control console, and a viewscreen. The actual Swinetrek set is a wide-spaced area, with the viewscreen and ship's walls and entrance portals raised several feet behind the crew area. This presented some difficulties at first. Jim Henson recalled, "I remember that the first time I saw the Pigs in Space set, I was horrified. There was enough room in there to play basketball, but we overcame the problem by using a very wide-angle lens."
- On Muppets Tonight, an updated version of the ship appeared in Pigs in Space: Deep Dish Nine. The crew of the new Swinetrek included Captain Pighead, Commander Piggy, and Craniac.
- The 2018 Muppet Babies series features a recurring spaceship called the Starship Piggy which loosely resembles the Swinetrek.
