The 1955 RAC Tourist Trophy took place on 17 September, on the roads around Dundrod, (County Antrim, Northern Ireland). It was also the fifth round of the F.I.A. World Sports Car Championship, however it was the first championship race following the horrendous tragedy at Le Mans. It was also the Golden Jubilee year for the Tourist Trophy. Going into the race, Ferrari were leading the Manufacturers Championship by four points from Jaguar. Victory for the Italian marque would put them in a strong position to win a third successive title.
