Knute Nelson (born Knud Evanger; February 2, 1843 – April 28, 1923) was a Norwegian-born American attorney and politician active in Wisconsin and Minnesota. A Republican, he served in state and national positions: he was elected to the Wisconsin and Minnesota legislatures and to the U.S. House of Representatives and the United States Senate from Minnesota, and served as the 12th governor of Minnesota from 1893 to 1895. Having served in the Senate for 28 years, 55 days, he is the longest-serving Senator in Minnesota's history.

Nelson is known for promoting the Nelson Act of 1889 to consolidate Minnesota's Ojibwe/Chippewa on a reservation in western Minnesota and break up their communal land by allotting it to individual households, with sales of the remainder to anyone, including non-natives. This was similar to the Dawes Act of 1887, which applied to Native American lands in the Indian Territory.

Knute Nelson was born out of wedlock in Evanger, near Voss, Norway, to Ingebjørg Haldorsdatter Kvilekval, who named him Knud Evanger. He was baptized by his uncle on their farm of Kvilekval, who recorded his father as Helge Knudsen Styve. This is unconfirmed. Various theories persist about Knud's paternity, including one involving Gjest Baardsen, a famous outlaw.

In 1843, Ingebjørg's brother Jon Haldorsson sold the farm where she and Knud lived, as he could not make a living, and emigrated to Chicago. Ingebjørg took Knud with her to Bergen, where she worked as a domestic servant. Having borrowed money for the passage, she and six-year-old Knud emigrated to the United States, arriving in Castle Garden in New York City on July 4, 1849. The holiday fireworks made a lasting impression on Knud, who was listed in immigration records as "Knud Helgeson Kvilekval". Ingebjørg Haldorsdatter claimed to be a widow (a story she stuck to until 1923). She and Knud traveled by the Hudson River to Albany, New York, and then via the Erie Canal to Buffalo.

They continued across the Great Lakes to Chicago. There her brother Jon, now working as a carpenter, took them in. While with him, Ingebjørg worked as a domestic servant and paid off her debt for passage in less than a year. Knud also worked, first as a house servant, then as a paperboy for the Chicago Free Press, which gave him an early education, both because he read the paper and because he learned street profanity.

In the fall of 1850, Ingebjørg married Nils Olson Grotland, also from Voss. The family of three moved to Skoponong, a Norwegian settlement in Palmyra, Wisconsin. Knud was given the surname Nelson after his stepfather, which eliminated the stigma of being fatherless.

By then 17 years old, Nelson was street-smart and rebellious, with a proclivity for profanity. He was accepted to the school held by Mary Blackwell Dillon, an Irish immigrant with linguistic talents. Nelson proved himself an apt though undisciplined student; he later recalled being whipped up to three times a day.

Still in his teens, Nelson joined the Democratic Party out of admiration for Stephen A. Douglas of Illinois. The family moved to the Koshkonong Settlement, which by 1850 had more than half of Wisconsin's Norwegian population of 5,000. Nils Olson had bad luck with land purchases and became sickly. Nelson picked up most of the work of the farm, but maintained his commitment to education. Olson was not supportive and Nelson often had to scrounge to find money for schoolbooks.
