Audun Boysen (10 May 1929 – 2 March 2000) was a Norwegian middle distance runner.

Boysen was a prominent 800 metre runner in the 1950s, and he won a bronze medal at the 1956 Summer Olympics, a silver medal at the 1958 European Championships and another bronze at the 1954 European Championships.

The same year he ran 800 metres (2,600 ft) in 1:45.9, setting a new Norwegian record.

That Norwegian record stood for 37 years until 3 July 1992 when it was broken by Atle Douglas (1:45.15) and Vebjørn Rodal (1:45.33).
