3 Body Problem is a 2024 science fiction drama series created by David Benioff, D.B. Weiss, and Alexander Woo for Netflix, adapting the first novel in Liu Cixin's celebrated Remembrance of Earth's Past trilogy — one of the most acclaimed works in contemporary science fiction. The series makes a significant structural departure from the source material, expanding the story's scope beyond its original Beijing setting to follow a group of scientists in Oxford and London while retaining the novel's central premise: that humanity has unknowingly made contact with an alien civilization, and the consequences will determine the species' fate.

The ensemble cast includes Jess Hong as Jin Cheng, John Bradley as Jack Rooney, Liam Cunningham as Thomas Wade, Eiza González as Auggie Salazar, and Benedict Wong in a central investigative role. The series opens in Cultural Revolution-era China with Ye Wenjie (Zine Tseng), whose traumatic experience of political violence leads her to make a decision with civilization-altering consequences. The interweaving of personal grief and scientific discovery with cosmic-scale stakes gives the series its emotional texture, grounding an otherwise vast narrative in recognizable human experience.

3 Body Problem was Netflix's most ambitious international genre series of 2024, praised for the scope of its production design and the ambition of its storytelling — particularly its willingness to engage with the novel's most challenging conceptual puzzles about physics, probability, and civilization. The VR sequences depicting the three-body simulation became some of the most discussed visual sequences on streaming that year. The series has been renewed for a second season. It streams exclusively on Netflix.
