'Cosmos: A Spacetime Odyssey' is a 2014 American science documentary television series. The show is a follow-up to the 1980 television series Cosmos: A Personal Voyage, which was presented by Carl Sagan on the Public Broadcasting Service and is considered a milestone for scientific documentaries.

This series was developed to bring back the foundation of science to network television at the height of other scientific-based television series and films. The show is presented by astrophysicist Neil deGrasse Tyson, who, as a young high school student, was inspired by Sagan.

The series loosely follows the same thirteen-episode format and storytelling approach that the original Cosmos used, including elements such as the 'Ship of the Imagination' and the 'Cosmic Calendar', but features information updated since the 1980 series, along with extensive computer-generated graphics and animation footage augmenting the narration.
