The 1984–85 Biathlon World Cup was a multi-race tournament over a season of biathlon, organised by the UIPMB (Union Internationale de Pentathlon Moderne et Biathlon). The season started on 10 January 1985 in Minsk, Soviet Union, and ended on 9 March 1985 in Holmenkollen, Norway. It was the eighth season of the Biathlon World Cup.
In Oberhof, the skating style of skiing made its introduction to biathlon. It was somewhat of a revolution as the skating style is quite a lot faster than the classic style. Some athletes did not adapt as quickly to the new style, and some nations, including West Germany and Norway, petitioned for a ban of the skating style.
There was originally going to be held a relay in Holmenkollen, but the relay had to be cancelled due to fog.
The World Cup scoring system was changed before this season.
