Oddbjørn Hagen (3 February 1908 – 25 June 1983) was a Norwegian skier who competed in Nordic combined and cross-country skiing.

Kalle Jalkanen on the final leg secured Finland the relay victory, six seconds ahead of the Norwegian team.

Hagen finished second in the 18 km, behind Sweden's Erik August Larsson, earning him a silver medal.

Hagen's consecutive world championships in Nordic combined would not be repeated until fellow Norwegian Bjarte Engen Vik won the event in 1999 and 2001.

In the 4 × 10 km relay in Sollefteå in 1934, Hagen had the final leg, and while battling with Sweden's Arthur Häggblad for the silver medal they both got off course and lost ten minutes.
