Steve Bren (born July 29, 1960) is a former American racing driver from Newport Beach, California.
After a fairly successful stint in US Formula Super Vee in 1985, Bren moved to the new American Racing Series (ARS) in 1986.
That year he also completed rookie orientation for the Indianapolis 500 but could not find a ride to make a qualification attempt.
He made two one-off starts in the CART Championship Car series in 1988 at Laguna Seca Raceway and 1990 at Long Beach, however he failed to finish either race.
In 2017, Bren was in trouble with the law for stalking Spangler in Idaho and also held in contempt of court for failing to appear at a civil case where he allegedly owed creditors over $5 million as part of his real estate developments.
