Good Omens is a fantasy comedy television series created by Neil Gaiman based on his and Terry Pratchett's 1990 novel. A co-production between Amazon MGM Studios and BBC Studios, the series was directed by Douglas Mackinnon, with Gaiman also serving as showrunner. Michael Sheen and David Tennant lead a large ensemble cast that also includes Jon Hamm, Miranda Richardson, Michael McKean, Derek Jacobi, Brian Cox, Benedict Cumberbatch, and Frances McDormand as the voice of God, who narrates the series.

Like the novel, Good Omens features various Christian themes and figures and follows various characters all trying to either encourage or prevent an imminent Armageddon, seen through the eyes of the angel Aziraphale and the demon Crowley.

All episodes of the first series were released on Amazon Prime Video on 31 May 2019, and aired weekly on BBC Two in the UK between 15 January and 19 February 2020. Although the show's first series was conceived and marketed as a limited series, it was renewed for a second series in June 2021; Sheen and Tennant returned, along with most of the cast and crew. The second series was released in its entirety on Amazon Prime Video on 28 July 2023. Good Omens was renewed for its third and final series in December 2023. Production of the third series was paused in September 2024 following multiple sexual assault allegations against Gaiman. In October 2024, it was announced that Gaiman would be leaving the production and the third series would be reduced to a single 90-minute episode.

Since its release, the series has been well received among critics, with praise for Sheen and Tennant's performances, faithfulness to its source material, and David Arnold's musical score, earning him two Primetime Emmy Awards nominations for Outstanding Music Composition and Original Main Title Theme.
