Georg Arnfinn Andersen (born 7 January 1963) is a Norwegian shot putter.

[2] In 1991 he originally won the silver medal at the World Championships in Tokyo with a throw of 20.81 metres, but as he was found using anabolic steroids he was retroactively disqualified.

[3][4] He returned from the doping suspension to compete at the 1995 World Championships, but failed to qualify for the final round there.

This ranks him second among Norwegian shot putters, only behind Lars Arvid Nilsen.

His son Stian Andersen competed at the 2005 World Youth Championships in octathlon.
