Marcus Armstrong

Marcus John Armstrong (born 29 July 2000) is a New Zealand motor racing driver who competes in the IndyCar series, driving the No. 66 Honda for Meyer Shank Racing. He competed in the FIA Formula 2 Championship between 2020 and 2022, and was the 2019 Formula 3 runner-up. He was a member of the Ferrari Driver Academy between 2017 and 2021.

Armstrong started single-seaters in 2014, and in the following year won his only single-seater title to date in the 2017 Italian F4 Championship whilst becoming runner-up in the 2017 ADAC Formula 4 Championship. He stepped to the FIA Formula 3 European Championship in 2018, ending fifth. The championship merged into the FIA Formula 3 Championship in 2019, and Armstrong became runner-up to teammate Robert Shwartzman. He was promoted to the 2020 Formula 2 Championship with ART Grand Prix but a difficult season saw him finish thirteenth. He also finished in the same position in the following year with DAMS, and came thirteenth again in the 2022 Formula 2 Championship with Hitech Grand Prix before making the switch to IndyCar.

Armstrong won the IndyCar Rookie of the Year award in 2023 and his first position in the series the following year whilst driving for Chip Ganassi Racing. In 2025, he moved to Meyer Shank Racing, earning his second podium that same year.
