Jack Doohan is an Australian racing driver, who competes in Formula One for Alpine.

Born and raised in Gold Coast, Queensland, Doohan is the son of five-time Grand Prix motorcycle World Champion Mick Doohan. He began kart racing aged nine in a go-kart gifted to him by Michael Schumacher, winning multiple national titles. Graduating to junior formulae in 2018, Doohan started his career in the F4 British Championship. After finishing runner-up to Joey Alders in the 2019–20 F3 Asian Championship, Doohan moved to FIA Formula 3 in 2020, where he finished runner-up to Dennis Hauger the following season with Trident. Doohan then progressed to FIA Formula 2, achieving several wins in both his 2022 and 2023 campaigns with Virtuosi, and finishing third in the latter.

A member of the Alpine Academy since 2022—previously a member of the Red Bull Junior Team—Doohan served as a reserve driver for Alpine in 2023 and 2024, replacing Esteban Ocon at the latter Abu Dhabi Grand Prix and making his Formula One debut. He was promoted to a full-time seat in 2025, replacing Ocon to partner Pierre Gasly. Doohan is contracted to remain at Alpine until at least the end of the 2025 season.
