Gattaca is a 1997 American dystopian science fiction film written and directed by Andrew Niccol in his feature directorial debut. It stars Ethan Hawke and Uma Thurman with Jude Law, Loren Dean, Ernest Borgnine, Gore Vidal, and Alan Arkin appearing in supporting roles. The film presents a future society driven by eugenics where children are conceived through genetic selection to ensure they possess the best hereditary traits of their parents. The principal character, Vincent Freeman, played by Hawke, was conceived outside the eugenics program and struggles to overcome genetic discrimination to realize his dream of going into space.

The film draws on concerns over reproductive technologies that facilitate eugenics, and the possible consequences of such technological developments for society. It also explores the idea of destiny and the ways in which it can and does govern lives. Characters in Gattaca continually battle both with society and with themselves to find their place in the world and who they are destined to be according to their genes.

The film's title is based on the letters G, A, T, and C, which stand for guanine, adenine, thymine, and cytosine, the four nucleobases of DNA. It was a 1997 nominee for the Academy Award for Best Art Direction and the Golden Globe Award for Best Original Score. A follow-up series was in development at Showtime, but has been cancelled as of 2023.
