Hjalmar Rued Holand (October 20, 1872 – August 6, 1963) was a Norwegian-American historian and author.

He was the author of a number of books and articles principally dealing with the history of Door County, Wisconsin, of the Upper Midwest, and with Norwegian-American immigration.

He was an early advocate of the now widely recognized realization that Vikings visited the New World in voyages that pre-dated Christopher Columbus.

Holand spent many years collecting the stories as he traveled to various Norwegian-American settlements in the Upper Midwest.

The results were De Norske Settlements Historie released in 1908 and Den Siste Folkevandring Sagastubber Fra Nybyggerlivet I Amerika published in 1930.
