The 1984 24 Hours of Le Mans was the 52nd Grand Prix of Endurance, and took place on 16 – 17 June 1984. It was also the third round of the 1984 World Endurance Championship. The works Rothmans Porsche team boycotted the 1984 Le Mans race due to a disagreement between Porsche and the Automobile Club de l'Ouest (ACO) over the fuel regulations, meaning that drivers such as multiple winners Jacky Ickx and Derek Bell were absent from the race for the first time in many years. Porsche originally stated that its contracted drivers would not be allowed to race with any other team, however they did relent only two or three weeks before the race. 1983 co-winner Vern Schuppan was the only member of the Rothmans team to race in 1984, eagerly snapped up by Kremer Racing to drive a Porsche 956B he would share with fellow Australian, Formula One World Champion Alan Jones, and experienced French driver Jean-Pierre Jarier.

Jaguar made its first official appearance at Le Mans for the first time since 1959 when Bob Tullius' Group 44 team brought over its two Jaguar XJR-5's powered by 6.0 litre Jaguar V12 engines from America. Group 44 racing, with the full backing of Jaguar, would compete in the IMSA GTP class. Before the decision to enter the race had been made, Jaguar had been concerned about the competitiveness of the XJR-5's against the turbocharged Porsche's and Ferrari powered Lancia's, especially with regard to top speed on the 6 km (3.7 mi) Mulsanne Straight. But those fears were put
