Circuit de Calafat is a motorsport facility located in Calafat, within the municipality of L'Ametlla de Mar in Tarragona, Catalonia, Spain. Built in 1974, the circuit was designed by Jordi Xiol as a privately-funded enterprise by Calafat, S.A., costing 30 million pesetas. Construction began early in 1974 and progressed through the summer, with the official inauguration on September 29, hosting a race for Formula Seat 1800 single seaters. The circuit is located 800 meters from the Mediterranean shore, with Barcelona's international airport approximately 80 minutes away by car.

In 1982, financial and legal difficulties caused the circuit to close temporarily. The following year, local courts awarded ownership to the municipality of L'Ametlla de Mar, with Calafat SA granted a 50-year lease to operate the facility. The circuit features a 3.25-kilometer (1.551-mile) main layout with 16 corners - nine right-handers and seven left-handers - connected by a 600-meter straightaway with a 10-meter track width. Being close to the sea, the circuit is largely flat. In recent years, Circuit Calafat has become a regular off-season test center for Formula E teams. The facility also features rallycross, rally, and autocross tracks, including a mixed 715-meter asphalt and gravel circuit with a jump and joker lap.
