Oscar Jack Piastri (born 6 April 2001) is an Australian racing driver who competes in Formula One for McLaren. Piastri has won nine Formula One Grands Prix across four seasons.
Born and raised in Melbourne, Piastri began his career in radio-controlled racing before moving into karting aged 10, where he won several regional titles. Graduating to junior formulae in 2016, Piastri won his first championship at the 2019 Formula Renault Eurocup with R-ace GP. He then won both the 2020 FIA Formula 3 and 2021 FIA Formula 2 Championships back-to-back with Prema, becoming the sixth driver in history to win the GP2/Formula 2 title in their rookie season. Piastri is the only driver in history to win Formula Renault, Formula Three, and Formula Two—or equivalent—championships in successive seasons.
A member of the Alpine Academy from 2020 to 2022, Piastri signed with McLaren in 2023 to partner Lando Norris, following a contract dispute with Alpine. He made his Formula One debut at the Bahrain Grand Prix, achieving his first career podium in his rookie season at the Japanese Grand Prix. Retaining his seat for 2024, Piastri achieved his maiden victory in Hungary, which he repeated in Azerbaijan, becoming the fifth Australian to win a Formula One Grand Prix. In 2025, he took seven further victories, as well as his maiden pole position at the Chinese Grand Prix, as he finished third in a title battle with Norris and Max Verstappen.
As of the 2026 Bahrain Grand Prix, Piastri has achieved nine race wins, six pole positions, nine fastest laps, and 28 podiums in Formula One. Piastri is contracted to remain at McLaren until at least the end of the 2028 season.
