A. J. "Peter" Kreis (January 19, 1900 Knoxville, Tennessee – May 25, 1934 Indianapolis, Indiana) was an Americanracecar driver. He and riding mechanic Robert Hahn were killed in a turn one accident while practicing for the 1934 Indianapolis 500. As he was entering the turn, a car in front of him spun, followed by Kreis' car spinning, possibly due to trying to avoid a collision. The car went over the outside wall backwards, tumbled, and hit a tree. Both men were dead when the ambulance arrived. Kreis was a wealthy contractor who would take a month off each year to drive in the 500.
