The Jeddah Corniche Circuit is a motor racing circuit that is being built in the Red Sea port city of Jeddah in Saudi Arabia. The circuit is scheduled to stage the inaugural Saudi Arabian Grand Prix on 5 December 2021 as the penultimate race on the 2021 Formula One season calendar. Named as the "fastest street track" on the Formula One calendar with Formula One cars simulated to have average speeds in excess of 250 km/h (160 mph), the track will be the second-longest track on the Formula One calendar, with only Spa-Francorchamps being longer. The circuit will be built on the Jeddah Corniche, also known as the Jeddah Waterfront, which is a 30 km coastal resort area of the city of Jeddah, adjoining the Red Sea.
