The season started on 14 December 1989 in Obertilliach, Austria, and ended on 18 March 1990 in Kontiolahti, Finland.

It was the 13th season of the Biathlon World Cup.

Originally, the World Championships were to be held in Minsk.

However, due to a lack of snow, only the individual competitions could be held, and the team, sprint and relay races were moved to Holmenkollen.

[2] On the last day in Holmenkollen, the men's relay was cancelled during the last leg due to fog; it was subsequently moved to Kontiolahti.
