Data is a fictional character in the Star Trek franchise. He appears in the television series Star Trek: The Next Generation (TNG) and the first and third seasons of Star Trek: Picard; and the feature films Star Trek Generations (1994), First Contact (1996), Insurrection (1998), and Nemesis (2002). Data is portrayed by actor Brent Spiner.

Data was found by Starfleet in 2338. He was the sole survivor on Omicron Theta in the rubble of a colony left after an attack from the Crystalline Entity. He is a synthetic life form with artificial intelligence, designed and built by Doctor Noonien Soong in his own likeness (likewise portrayed by Spiner). Data is a self-aware, sapient, sentient and anatomically fully functional male android who serves as the second officer and chief operations officer aboard the Federation starship USS Enterprise-D and later the USS Enterprise-E.

His positronic brain allows him impressive computational capabilities. He experienced ongoing difficulties during the early years of his life with understanding various aspects of human behavior and was unable to feel emotion or understand certain human idiosyncrasies, inspiring him to strive for his own humanity. This goal eventually led to the addition of an "emotion chip", created by Soong, to Data's positronic net. Although Data's endeavor to increase his humanity and desire for human emotional experience is a significant plot point (and source of humor) throughout the series, he consistently shows a nuanced sense of wisdom, sensitivity and curiosity, garnering respect from his peers and colleagues.

Data is in many ways a successor to the original Star Trek's Spock (Leonard Nimoy), in that the character has superior mental skills and offers an "outsider's" perspective on humanity.

Star Trek: The Next Generation (TNG) is an American science fiction television series created by Gene Roddenberry. It originally aired from September 28, 1987, to May 23, 1994, in syndication, spanning 178 episodes over seven seasons. The third series in the Star Trek franchise, it was inspired by Star Trek: The Original Series. Set in the latter third of the 24th century, when Earth is part of the United Federation of Planets, it follows the adventures of a Starfleet starship, the USS Enterprise (NCC-1701-D), in its exploration of the Alpha quadrant and Beta quadrant in the Milky Way galaxy.

In the 1980s, Roddenberry—who was responsible for the original Star Trek, Star Trek: The Animated Series (1973–1974), and the first of a series of films—was tasked by Paramount Pictures with creating a new series in the franchise. He decided to set it a century after the events of his original series. The Next Generation featured a new crew: Patrick Stewart as Captain Jean-Luc Picard, Jonathan Frakes as William Riker, Brent Spiner as Data, Michael Dorn as Worf, LeVar Burton as Geordi La Forge, Marina Sirtis as Deanna Troi, Gates McFadden as Dr. Beverly Crusher, Denise Crosby as Tasha Yar, Wil Wheaton as Wesley Crusher, and a new Enterprise.

Space: The final frontier. These are the voyages of the starship Enterprise. Its continuing mission: to explore strange new worlds, to seek out new life and new civilizations, to boldly go where no one has gone before.

The show was very popular, reaching almost 12 million viewers in its 5th season, with the series finale in 1994 watched by over 30 million viewers. Due to its success, Paramount commissioned Rick Berman and Michael Piller to create a fourth series in the franchise, Star Trek: Deep Space Nine, which launched in 1993. The characters from The Next Generation returned in four films: Star Trek Generations (1994), Star Trek: First Contact (1996), Star Trek: Insurrection (1998), and Star Trek: Nemesis (2002), and in the television series Star Trek: Picard (2020–2023). The series is also the setting of numerous novels, comic books, and video games. It received many accolades, including 19 Emmy Awards, two Hugo Awards, one Peabody Award, and six Saturn Awards, including a Lifetime Achievement Award for the entire cast in 2024.

In 2013, the Writers Guild of America ranked Star Trek: The Next Generation #79 – along with Upstairs, Downstairs, Monty Python's Flying Circus and Alfred Hitchcock Presents – on their list of the 101 Best Written TV Series.
