Daniel Greysolon, Sieur du Lhut (c. 1639 – 25 February 1710) is a French soldier and explorer who is the first European known to have visited the area where the city of Duluth, Minnesota is now located and the headwaters of the Mississippi River near Grand Rapids.
His name is sometimes anglicized as "DuLuth" and is the namesake of Duluth, Minnesota as well as Duluth, Georgia.
