Stefan Grand Prix was a proposed Serbian Formula One team named after its creator, Zoran Stefanović. The team was attempting to compete in the 2010 Formula One season. Its initial application was one of those rejected in July 2009 and although the team persisted in its attempts to gain an entry, it did not appear on the final entry list published in March 2010. The team also applied unsuccessfully to compete in the 2011 and 2015 seasons.
In November 2009, Toyota officially backed out of the championship, following a manufacturer exodus led by Honda and BMW. Despite initial plans not to sell the team on, Stefanović acquired the rights to use the team's chassis, gearbox and the 2010 spec engine. It also employed several former Toyota team members, then out of work after being made redundant by Toyota. With the vacancy left by Toyota, the FIA moved to fill the thirteenth and final grid position, which was contested between Stefanović and Peter Sauber, after BMW sold the team back to him. Sauber was eventually accepted to the grid. Stefanović was later reported as pursuing a 2010 grid position despite the thirteenth grid position having been awarded to Sauber.
