The 1975 Spanish Grand Prix was a Formula One motor race held at Montjuïc circuit on 27 April 1975. It was race 4 of 14 in both the 1975 World Championship of Drivers and the 1975 International Cup for Formula One Manufacturers.

Track staff worked overnight to fix the barriers, and to make sure everything would be fixed in time for qualifying on Saturday, some of the teams sent out mechanics to help. The drivers, though, still were not convinced, but the race organizers threatened legal action if no race was run. This, and rumors that the Guardia Civil would seize the cars which were in the paddock, which was at Montjuïc Stadium, forced the drivers to call off the strike. The defending World Champion Emerson Fittipaldi, however, was still furious. He did the minimum three
