3 Body Problem is an American science fiction television series created by David Benioff, D. B. Weiss and Alexander Woo. The third streaming adaptation of the Chinese novel series Remembrance of Earth's Past by former computer engineer Liu Cixin, its name comes from its first volume, The Three-Body Problem, named after a classical physics problem dealing with Newton's laws of motion and gravitation. The eight-episode first season was released on Netflix on March 21, 2024.

The series follows a diverse cast of characters, primarily scientists, who all come into with an extraterrestrial civilization, leading to various threats and humanity-wide changes. While the two previous series adaptations, the animated The Three-Body Problem in Minecraft (2014–2020) and the live-action Three-Body (2023), were exclusively in the novels' original Mandarin, 3 Body Problem is mostly in English and modifies part of the original works' Chinese setting to include foreign characters and locations, mainly the United Kingdom.

Benioff and Weiss' first television project since the conclusion of their series Game of Thrones (2011–2019), it received positive reviews, with praise towards its cast, ambition and production values. The series received six Primetime Emmy Award nominations, including Outstanding Drama Series. In May 2024, it was renewed for both second and third seasons.
