The 2008 Macau Grand Prix (formally the 55th Windsor Arch Macau Grand Prix) was a motor race for Formula Three cars that was held on the streets of Macau on 16 November 2008. Unlike other races, such as the Masters of Formula 3, the 2008 Macau Grand Prix was not a part of any Formula Three championship, but was open to entries from all Formula Three championships. The race itself was made up of two races: a ten-lap qualifying race that decided the starting grid for the fifteen-lap main race. The 2008 race was the 55th running of the Macau Grand Prix and the 26th for Formula Three cars.
