Kyle XY is an American science fiction television series created by Eric Bress and J. Mackye Gruber and produced by ABC Studios. The central character is a teenage boy (Matt Dallas) who awakens naked in a forest outside Seattle, Washington, with no more knowledge or abilities than a newborn and no belly button. He is taken in by a family and given the name Kyle. The series follows Kyle as he tries to solve the puzzles of who he is and why he has no memory before that day. Although set in present-day Seattle, the series was filmed in the Vancouver, British Columbia area.

The show premiered June 26, 2006, on the ABC Family cable channel. Episodes were also broadcast on the ABC network for the first season, but only for part of the second season, after which it was only seen on ABC Family.

After the 10-episode debut season on ABC Family during summer 2006, news reported a total of 23 new episodes were ordered for the second season, which started on June 11, 2007, with rebroadcasts on ABC beginning on June 15, 2007.

On October 5, 2007, TV Guide reported that ABC family had renewed Kyle XY for a third season of 10 episodes, which began airing on January 12, 2009.

On January 31, 2009, ABC Family announced that Kyle XY would not be returning for a fourth season. The season finale of the show aired on Monday, March 16, 2009, at 9/8c on ABC Family, leaving several unresolved dramatic cliffhangers. Following the last episode, writer Julie Plec revealed what had been planned for further seasons. She also noted that the season three DVD would contain a "mini wrap-up" feature for the series. The "wrap-up" is called "Kyle XY: Future Revealed", with the writers and actors explaining their plans for future episodes and what would have ultimately happened in the series ending.
