Da Ali G Show is an English satirical sketch comedy television series created by and starring English comedian Sacha Baron Cohen. In the series, Baron Cohen plays three unorthodox journalists: faux-streetwise poseur Ali G, Kazakh reporter Borat Sagdiyev, and gay Austrian fashion enthusiast Brüno Gehard. These characters conduct real interviews with unsuspecting people, many of whom are celebrities, high-ranking government officials, and other well-known figures, during which they are asked absurd and ridiculous questions.

The first (2000) series originally aired on Channel 4 in the UK, and the second and third (2003–2004) series on HBO in the United States. The second series was known as Ali G in da USAiii in the UK and Australia. In 2005, HBO stated they had no plans to make an additional series of the show.

Baron Cohen has gone on to make four films featuring each of his three characters from the show: Ali G Indahouse (2002), Borat: Cultural Learnings of America for Make Benefit Glorious Nation of Kazakhstan (2006), Brüno (2009) and Borat Subsequent Moviefilm: Delivery of Prodigious Bribe to American Regime for Make Benefit Once Glorious Nation of Kazakhstan (2020).

In 2014, FXX reaired the show (including episodes unaired in the United States) under the branding Ali G: Rezurection.
