"Relativity" is the 118th episode of the American science fiction television series Star Trek: Voyager airing on the UPN network. It is the 24th episode of the fifth season.

USS Voyager (NCC-74656) is the fictional Intrepid-class starship which is the primary setting of the science fiction television series Star Trek: Voyager. It is commanded by Captain Kathryn Janeway. Voyager was designed by Star Trek: Voyager production designer Richard D. James and illustrator Rick Sternbach. Most of the ship's on-screen appearances are computer-generated imagery (CGI), although models were also sometimes used. The ship's motto, as engraved on its dedication plaque, is a quote from the poem "Locksley Hall" by Alfred, Lord Tennyson: "For I dipt in to the future, far as human eye could see; Saw the vision of the world, and all the wonder that would be."
