Dean MacDonald (born 6 December 2000) is a British racing driver who competes for JP Motorsport in the GT World Challenge Europe Sprint Cup.

[2] MacDonald enjoyed a successful karting career, becoming the youngest Comer Cadet winner of the Scottish Championship and later winning the Iame International Final in the X30 Pro class in 2019.

In the winter of 2017, MacDonald was a finalist for the Porsche Carrera Cup Great Britain Junior Scholarship shootout, becoming the youngest member of that year's prospective class.

[5] However, MacDonald's program with Steller wouldn't last the entire season, as the team were forced to skip the round at Spa after parts delays derailed a planned upgrade to their Toyota GT86-based entry.

[7] MacDonald returned to McLaren machinery in 2019, embarking on his third British GT season with HHC Motorsport, paired with Callum Pointon.

Alongside Gus Bowers, MacDonald joined United Autosports' effort in the GT4 European Series, with the two pairing up in the team's #32 entry.

In the Endurance Cup, MacDonald switched to fellow McLaren competitors Optimum Motorsport, driving alongside Sam De Haan and Charlie Fagg.
