Alexander Philippe Albon Ansusinha (Thai: อเล็กซานเดอร์ อัลบอน อังศุสิงห์; born 23 March 1996) is a Thai and British racing driver who competes 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 World Cup and European Championship in 2010—Albon graduated to junior formulae. Following 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 FIA Formula 2 in 2017, Albon finished third in the championship the following season with DAMS.

Previously a member of the Red Bull Junior Team from 2008 to 2012, Albon signed for Toro Rosso in 2019, making his Formula One debut at the Australian Grand Prix; after 12 races, he was promoted to parent team Red Bull, replacing Pierre Gasly to partner Max Verstappen. In 2020, he became the first Thai driver to achieve a podium in Formula One at the Tuscan Grand Prix, which he repeated in Bahrain. Replaced by Sergio Pérez in 2021, Albon continued as a reserve driver for Red Bull and the re-branded AlphaTauri, contesting DTM with Red Bull AF Corse alongside Liam Lawson. Albon signed for Williams in 2022 to replace George Russell, ending his association with Red Bull at the conclusion of his first season. He remained at Williams through the 2023, 2024, and 2025 seasons, finishing eighth—the highest of the midfield drivers—in the latter.

As of the 2026 Japanese Grand Prix, Albon has achieved two podium finishes and one fastest lap in Formula One. Albon is contracted to remain at Williams until at least the end of the 2027 season.
