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

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.

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.
