Knut Alvsson (1455 – 18 August 1502) was a Norwegian nobleman and landowner. He was the country's foremost Norwegian-born noble in his time and served as fief-holder in southern-central Norway.
He was heir of the Sudreim claim to the Norwegian throne in accordance with the order of succession agreed to by Norwegian nobility and religious leadership when the Sverre dynasty became extinct. From 1497 to 1499 he served as commander of Akershus Fortress but was removed in 1499 when he lost King Hans' confidence. In 1501 he led a rebellion against King Hans in Norway. He met his death at the hands of pro-Danish Henrich Krummedige’s men in spite of a promise of safe conduct, effectively weakening the rebellion severely as well as ending a feud which had started with their fathers, Hartvig Krummedige and Alv Knutsson.
