Alexander Albon Ansusinha (Thai: อเล็กซานเดอร์ อัลบอน อังศุสิงห์; RTGS: Aleksandoe Anbon Angsusing, pronounced [ʔà lék saːn dɤː ʔan bɔːn ʔaŋ sùʔ sǐŋ]; born 23 March 1996) is a Thai and British racing driver, currently competing under the Thai flag in Formula One for Williams.

Born in Westminster and raised in Suffolk, Albon is the son of English racing driver Nigel Albon and his Thai wife, as well as the nephew of Mark Albon. After a successful karting career—culminating in his victories at the junior direct-drive Karting World Cup and Karting European Championship in 2010—Albon graduated to junior formulae. After three seasons in the Formula Renault Eurocup from 2012 to 2014, Albon progressed to the FIA Formula 3 European Championship in 2015. He moved to the GP3 Series for 2016, finishing runner-up to Charles Leclerc in his rookie season with ART. Graduating to Formula 2 in 2017, Albon finished third in the championship the following season with DAMS.

Previously a member of the Red Bull Junior Team in 2012, Albon signed for Toro Rosso in 2019, making his Formula One debut at the Australian Grand Prix. After 12 races with Toro Rosso, Albon was promoted to parent team Red Bull, replacing Pierre Gasly to partner Max Verstappen. In 2020, he took his maiden podium at the Tuscan Grand Prix, becoming the first Thai driver to score a podium finish in Formula One; he repeated this feat in Bahrain. Replaced by Sergio Pérez in 2021, Albon continued as a reserve driver for Red Bull and the re-branded AlphaTauri. Albon signed for Williams in 2022 to replace George Russell, ending his association with Red Bull at the conclusion of his first season with the team. He remained at Williams through the 2024 season.

As of the 2024 Las Vegas Grand Prix, Albon has achieved two podiums in Formula One. Albon is set to remain at Williams until at least the end of the 2026 season.

Outside Formula One, Albon competed in the 2021 Deutsche Tourenwagen Masters for Red Bull AF Corse alongside Liam Lawson.
