The 1991–92 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 19 December 1991 in Hochfilzen, Austria, and ended on 22 March 1992 in Novosibirsk, Russia. It was the fifteenth season of the Biathlon World Cup.
The men's individual and women's sprint were moved from Holmenkollen, Norway to Skrautvål, Norway, due to rain and fog, with the planned relays being cancelled. The fifth round of the World Cup was originally going to be held in Kokkola, Finland, but were moved to Skrautvål due to a lack of snow.
