The 2008–09 A1 Grand Prix of Nations, Great Britain was an A1 Grand Prix race at Brands Hatch, England. It was set to be the final race of the 2008-09 A1 Grand Prix season, but became the season finale, due to the cancellation of the Mexican round due to the 2009 swine flu pandemic. Ultimately, it would be the last race for A1GP as bankruptcy followed later in the year. A1 Team Ireland became the fourth A1 Grand Prix champions, with a double pole position, and double victory, to take Ireland's first international motor racing championship.
