Andor, also known as Star Wars: Andor and Andor: A Star Wars Story for its second season, is an American science fiction political spy thriller drama television series created by Tony Gilroy for the streaming service Disney+. It is part of the Star Wars franchise and a prequel to the film Rogue One (2016), which itself is a prequel to the original Star Wars film (1977). The series follows thief-turned-rebel spy Cassian Andor during the formative five years that lead to the events of the two films, exploring how he becomes radicalized against the Galactic Empire and how the wider Rebel Alliance is formed.

Diego Luna reprises his role as Cassian Andor from Rogue One and serves as an executive producer. The series also stars Kyle Soller, Adria Arjona, Stellan Skarsgård, Fiona Shaw, Genevieve O'Reilly, Denise Gough, Faye Marsay, Varada Sethu, Elizabeth Dulau, Ben Mendelsohn, Benjamin Bratt, and Alan Tudyk. Lucasfilm announced a series focused on Andor in 2018, with Luna attached and Stephen Schiff hired as showrunner. Schiff was replaced by Rogue One co-writer Gilroy as creator and showrunner in April 2020. Filming took place at Pinewood Studios in London and on location around the UK, with Neal Scanlan returning from Rogue One to provide practical effects. The first season, which tells a year of Andor's story when he first becomes a revolutionary, was filmed from November 2020 to September 2021 during the COVID-19 pandemic. The second season covers the next four years leading up to Rogue One, and was filmed from November 2022 to February 2024 with breaks and delays due to the 2023 Hollywood labor disputes. Nicholas Britell composed the series' original score for the first season, while Brandon Roberts composed for the second season.

Andor premiered on September 21, 2022, episodes of the season were released weekly through November 23. The second and final season premiered on April 22, 2025, with three episodes released weekly until May 13. The series has received critical acclaim for its writing, performances, cinematography, production values, themes, and its darker, more mature and grounded tone compared to other Star Wars properties. The first season was nominated for three Primetime Emmy Awards including Outstanding Drama Series.
