"Marauders" is the sixth episode of the second season of the American science fiction television series Star Trek: Enterprise, the 32nd episode overall. It first aired on October 30, 2002, on the UPN network within the United States. The story was created by executive producers Rick Berman and Brannon Braga with a teleplay by David Wilcox. A similar premise had been included in the original pitch for Star Trek by Gene Roddenberry.

Set in the 22nd century, the series follows the adventures of the first Starfleet starship Enterprise, registration NX-01. In this episode, while in search of deuterium, Enterprise discovers a mining colony that is being controlled by Klingons who are bullying the inhabitants and hoarding their supplies. The crew conduct repairs on the colony and train the colonists to fight off the Klingons.

This episode was mostly filmed on location in a quarry in Ventura County, California, and the majority of the guest stars were stunt performers. Both Larry Cedar and Bari Hochwald had previously appeared in different episodes of Deep Space Nine and Voyager. "Marauders" was watched by 5.6 million viewers, the second highest audience for an episode of the second season. Reviews were mixed, with some critics responding negatively to the lack of consequences from the fighting sequences while another praised the characters interactions and felt it was a good example of the western genre.

Captain Jonathan Archer (Scott Bakula), Sub-Commander T'Pol (Jolene Blalock), and Commander Charles "Trip" Tucker III (Connor Trinneer) fly down to a small colony of 76 miners in order to trade for deuterium. They initially try to barter with Tessic (Larry Cedar), the colony's leader, but he appears reluctant to part with any of the 80,000 liters in inventory, which is being held for 'someone else'. After negotiations however, a deal is struck − 200 liters of deuterium for four power cells and whatever medical supplies Enterprise can spare, on the proviso that the Enterprise crew can fix two offline pumps in two days.
