1977 World Sportscar Championship

The 1977 World Sports Car Championship season was the 25th season of FIA World Sportscar Championship motor racing. It featured two separate World Championship series.

• The 1977 World Championship for Sports Cars, which was contested by Group 6 Two-Seater Racing Cars
• The 1977 World Championship for Makes, which was open to cars from various production-based categories including Group 5 Special Production Cars

In 1978 the World Championship of Makes would become the sole international series, while the cars used in the World Championship for Sports Cars would be used in the revival of the European Sportscar Championship. The European Championship was discontinued again at the end of the 1978 season.
