John Rostek (November 12, 1925 - December 29, 1969) was a NASCAR driver from Fort Collins, CO. Despite racing in just six Nextel Cup Series events in his career, Rostek earned one victory, one pole and three top-tens.
Five of his six races came in 1960, when Rostek debuted at Daytona, racing in the Daytona 500 qualifier. But a crash on the fifth lap would end his chances of a good finish and making the 500, finishing 39th. But his rebound was amazing. In his next race, Phoenix, Rostek took the lead midway through the event, led 58 laps and pulled away to a shocking victory. He proved it was no fluke later in the year, finishing 3rd at Hanford and 7th at Montgomery after leading seven laps and starting on the pole.
Rostek's final race came in 1963, racing at Riverside. Starting 27th in the forty-four car field, Rostek seemed poised for another top-ten finish before a late crash sidelined him to 16th.
