Westworld is an American dystopian science fiction Western television series created by Jonathan Nolan and Lisa Joy that first aired on October 2, 2016, on HBO. It is based upon the 1973 film of the same name written and directed by Michael Crichton and loosely upon its 1976 sequel, Futureworld.

The story begins in Westworld, a fictional, technologically advanced Wild-West-themed amusement park populated by android "hosts". The park caters to high-paying guests who may indulge their wildest fantasies within the park without fear of retaliation from the hosts, who are prevented by their programming from harming humans. Later on, the series' setting expands to the real world, in the mid-21st century, where people's lives are driven and controlled by a powerful artificial intelligence named Rehoboam.
