Guenther Steiner is a motorsport team manager and former mechanic hailing from Merano in northern Italy. From 2014 to the end of 2023 he was the team principal of the Haas Formula One Team, having previously been managing director of Jaguar Racing and technical operations director of its subsequent incarnation, Red Bull Racing. In 2014, Guenther persuaded Gene Haas, owner of Haas Automation and NASCAR championship winning team Stewart-Haas Racing, to enter Formula 1.

With their entry in the 2016 season, Haas became the first American constructor to compete in F1 in 30 years. The team took eight points at the 2016 Australian Grand Prix with a 6th-place finish, becoming the first American entry, and the first constructor overall since Toyota Racing in 2002, to score in their debut race. Steiner is also a prominent figure in the cast of the successful Netflix series Drive to Survive.
