The 1976 Spanish Grand Prix was a Formula One motor race held at the Circuito del Jarama in Madrid on 2 May 1976. The race was the fourth round of the 1976 Formula One season.

Initially the declared winner was Austrian Ferrari driver Niki Lauda driving a Ferrari 312T2 extending his Drivers' Championship lead to 23 points after first across the line James Hunt had his McLaren M23 disqualified in post-race scrutineering. Swedish driver Gunnar Nilsson took his Lotus 77 to second place with Carlos Reutemann finishing third in his Brabham BT45.

McLaren appealed the disqualification and in July the appeal was upheld and Hunt re-instated as winner of the Spanish Grand Prix.
