Kajsa Vickhoff Lie started third in the downhill race in Kvitfjell and took the lead when she crossed the finish line in 1:32.36.
Then there was a nervous wait where one by one the other riders came in after her.
The Norwegian eventually won 29 hundredths ahead of runner-up Sofia Goggia and third was Corinne Suter.
- It is completely insane.
Have you seen this mood?, says Vickhoff Lie to TV2.
It was Norway's first downhill victory in the World Cup on the women's side and it came at home in Kvitfjell.
It was also Vickhoff Lie's first win in the World Cup, previously she had two second places as her best result.
- It has been a dream all my life to be able to do this.
It couldn't have gone better, says Vickhoff Lie to TV2.
Continued pursuit of records for Shiffrin
Mikaela Shiffrin, who has 85 World Cup victories and is chasing Ingemar Stenmark's record of 86, finished fifth.
Thus, she can continue to chase the Alpine victory record in the World Cup.
