Jack Aitken is a British-Korean racing driver who competes in the FIA World Endurance Championship for Cadillac Hertz Team JOTA, sharing the #38 Cadillac V-Series.R with Earl Bamber and Sebastien Bourdais.

Aitken made one Formula 1 start at the 2020 Sakhir Grand Prix as a substitute for Williams. He moved fully into sports car racing and, across 22 IMSA starts with Cadillac, registered three victories, two pole positions, and finished runner-up in the 2025 GTP standings alongside Bamber. He has made four Le Mans 24 Hours appearances, including three in the Hypercar class.

The 2026 WEC campaign is Aitken's first full season in the world championship. He continues to race with Action Express Racing in IMSA in parallel, making him one of the busier dual-programme drivers in the Cadillac ecosystem.
