Mário Haberfeld (born January 25, 1976, in São Paulo) is a Brazilian auto racing driver.^[1]

After winning the British Formula 3 Championship in 1998, he drove in Formula 3000 from 1999 until 2002. He posted some decent results but struggled his first season driving for the McLaren junior team failing to score a single point while teammate Nick Heidfeld won the series championship.

Haberfeld also tested for a number of Formula One teams, including Stewart Grand Prix in 1998, McLaren in 1999, and Jordan in 2001.

In 2003 he moved to the Champ Car World Series driving for Mi-Jack Conquest Racing. His team shared information with a fellow rookie team driving a Reynard chassis, Emerson Fittipaldi's team with future F1 driver Tiago Monteiro. He scored a best finish of 4th on his first start in St. Petersburg. In 2004 he was a field-filler driving the lone Reynard in the series for Derrick Walker, but proved his worth with another pair of top-five finishes. No one picked him up for 2005, but he drove a few Grand-Am races for Tuttle Team Racing at the end of the year. He then drove in the Rolex Grand Am series for Adrian Fernández who was also his teammate.

In 2019 Haberfeld raced in the Jaguar I-Pace eTrophy, for Jaguar Brazil Racing, temporarily replacing Cacá Bueno.^[2]
