"Horizon" is the twentieth episode of the second season of the science fiction television series Star Trek: Enterprise, and originally aired on April 16, 2003, on UPN. The episode was written by André Bormanis and directed by James A. Contner. The episode's guest stars included Nicole Forester, who had previously appeared in Star Trek: Deep Space Nine; Joan Pringle; and Corey Mendell Parker.
Set in the 22nd century, the series follows the adventures of the first Starfleet starship Enterprise, registration NX-01. When the ship detours to observe volcanic activity on a planet, Ensign Mayweather (Anthony Montgomery) takes the opportunity to visit his family on board the E.C.S. Horizon.
Montgomery had previously suggested the appearance of Mayweather's parents at the end of season one, and was pleased to see them introduced. Several sets to create the Horizon were created on a soundstage, with the related scenes filmed in the second half of the episode's shoot after the main cast were dismissed, with the exception of Montgomery. Critical response was mixed, and the episode received the lowest ratings for a first-run episode of the series so far, viewed by 3.36 million viewers.
