Ann Druyan (born June 13, 1949) is an acclaimed American documentary producer and director renowned for her expertise in the communication of science. Her notable work includes co-writing the 1980 PBS documentary series Cosmos, hosted by Carl Sagan, whom she married in 1981. Druyan's influence extends to the creation, production, and writing of the 2014 sequel, Cosmos: A Spacetime Odyssey and its sequel series, Cosmos: Possible Worlds, along with the book of the same name. She also directed episodes of both series.

In the late 1970s, Druyan took on the role of creative director for NASA's Voyager Interstellar Message Project, resulting in the iconic golden discs affixed to the Voyager 1 and Voyager 2 spacecraft. She is also the author of the novel A Famous Broken Heart (1977), and has co-written several best-selling non-fiction books with Sagan, among them Comet and Shadows of Forgotten Ancestors. Druyan's work consistently emphasizes a sense of awe and wonder about the cosmos without necessitating the concept of a god.
