Sartell is a city in Benton and Stearns counties in the U.S. state of Minnesota. It is part of the St. Cloud Metropolitan Statistical Area. The population was 15,876 at the 2010 census, making it St. Cloud's most populous suburb and the largest city in the central Minnesota region after St. Cloud.
Sartell got its start as a small town on the Mississippi River with lumber and a paper company as its main industries. The present site of the city was originally dubbed "The Third Rapids", as it was the third set of rough waters that French fur traders encountered as they traveled north from Saint Anthony Falls in Minneapolis.
One of the first people to settle in the fledgling town was Joseph B. Sartell, who arrived in 1854 and worked as a millwright at a local sawmill. In 1877, he opened a flour mill at the nearby Watab River, and in 1884 he started the Sartell Brothers Lumber Company with his sons.
