The 1955 British Grand Prix was a Formula One motor race held at Aintree on 16 July 1955.

British driver Stirling Moss led a Mercedes 1–2–3–4 domination of the race, to win his first Formula One race narrowly ahead of his illustrious Argentine teammate Juan Manuel Fangio.

Several people, including Moss, believed that the Argentine allowed his British protégé to claim his debut win in front of his home crowd.

In the wake of the Le Mans disaster, the French, German, Swiss and Spanish Grands Prix which were to take place at existing circuits had all been cancelled.

The Aintree circuit was an all-new circuit around the Grand National horse racing course in Liverpool; it was built to be at the time one of the safest and most modern racing facilities in Europe.
