The 1975 Spanish Grand Prix was a Formula One motor race held at Montjuïc circuit on 27 April 1975.

Argentine racer Carlos Reutemann was declared third in his Brabham BT44B, a lap behind the race leaders after a penalty was given to Jean-Pierre Jarier.

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 two Ferraris of Niki Lauda (on pole) and Clay Regazzoni qualified on the front row, but their glory would not last long.

Patrick Depailler also retired on the first lap because of suspension damage, and Wilson Fittipaldi and Arturo Merzario withdrew in protest.

On lap four, the engine in Jody Scheckter's Tyrrell blew, and the oil dumping onto the circuit caused Alan Jones and Mark Donohue to crash.

Jean-Pierre Jarier and Brambilla stopped to change tyres, whilst Tom Pryce and Tony Brise tangled.

The rear wing on Stommelen's Embassy Hill broke, sending him into the barrier, ironically at the point that his own mechanics had worked on.

Four people were killed by Stommelen's flying car: fireman Joaquín Benaches Morera, spectator Andrés Ruiz Villanova, and two photo-journalists, Mario de Roia and Antonio Font Bayarri.

On lap 29, the race was halted with Mass the winner, Ickx second, and Jean-Pierre Jarier crossed the line in third position.

After the race, stewards found that Jarier had overtaken in a portion of the track covered by a yellow flag caution.
