The 1984 European Rallycross Championship season was the ninth season of the FIA European Rallycross Championship under that name and the twelfth season overall since it began as the Embassy/ERA European Rallycross Championship. It was held across nine rounds starting at the Nordring in Austria on April 8 and ending at the LyngÃÂ¥s Motorbane in Norway on October 7.
The champions were Anders Norstedt (Division 1) and Martin Schanche (Division 2). Schanche won six of the nine rounds on the Division 2 schedule to guarantee himself the title. In Division 1 Norstedt had an equal number of wins to his closest title rival Lars Nyström. The highest placed driver with no wins in any class was Olle Arnesson, the Division 2 third-placer.
