Alv Knutsson (c. 1420–1496) was a Norwegian nobleman who descended on his father's side from the influential and wealthy Swedish Tre Rosor noble family. He was a member of the Norwegian council of the realm and also served as commander of the royal castle in Bergen. Alv Knutsson is most famous for his involvement in the Krummedige-Tre Rosor feud. He was the father of the Norwegian rebel leader Knut Alvsson.[1] [2]
