The 1975 ShellSPORT 5000 European Championship was a motor racing series for Formula 5000 cars. The series was organized in the United Kingdom by the British Racing and Sports Car Club, but also incorporated European rounds. It was the seventh and last in a sequence of annual European Formula 5000 Championships, and the first to be contested as the ShellSPORT 5000 European Championship. The 1975 championship was won by Teddy Pilette, driving a Lola T400.

Formula 5000 was an open wheel, single seater auto-racing formula that ran in different series in various regions around the world from 1968 to 1982. It was originally intended as a low-cost series aimed at open-wheel racing cars that no longer fit into any particular formula. The '5000' denomination comes from the maximum 5.0 litre engine capacity allowed in the cars, although many cars ran with smaller engines. Manufacturers included McLaren, Eagle, March, Lola, Lotus, Elfin, Matich and Chevron.
