23 athletes represented Norway. It was the nation's third appearance in the sport as well as the Olympics.
Ferdinand Bie, who had originally won the silver medal in the pentathlon, was awarded gold after
Jim Thorpe was disqualified. When Thorpe was reinstated in 1982, Bie retained his gold medal in the event and became co-champions with Thorpe. In 2022, in consultation with surviving members of Bie's family, the IOC reinstated Thorpe as the sole winner of the event, as all his competitors had always wanted. Bie's medal was the only one won by Norway in athletics in 1912 and was the nation's second athletics gold medal.
Arne Halse, who had previously held Norway's best athletics result with a silver medal in the
1908 javelin throw, placed 7th in the javelin and 5th in the two-handed version of the event. Norway also had two fourth-place finishes, in the triple jump and team cross country. Ranks given are within that athlete's heat for running events. == Cycling==
