St. Croix County is a county in the U.S. state of Wisconsin. As of the 2020 census, the population was 93,536. Its county seat is Hudson. The county was created in 1840 (then in the Wisconsin Territory) and organized in 1849. St. Croix County is part of the Minneapolis–St. Paul–Bloomington, MN–WI Metropolitan Statistical Area. Between 2000 and 2010, it was Wisconsin's fastest-growing county. Its growth has continued since 2010 in part due to people moving out of the central Minneapolis–Saint Paul counties and into St. Croix County.

History

St. Croix County was created on August 3, 1840,Laws of the Territory of Wisconsin. Belmont and Milwaukee, 1836–1848. no. 20, sec. 1/pp. 25-6 by the legislature of the Wisconsin Territory. It was named after the river on its western border. Sources vary on the name's origin. The St. Croix River may have been named after an explorer named St. Croix who drowned at the river's mouth in the late 17th century. According to another account, Father Hennepin gave this region the French name Ste Croix (Holy Cross) because of the burial markers at the river's mouth. History of St. Croix County

The part of St. Croix County allocated to Wisconsin became the parental county to Pierce and Polk Counties, and formed significant portions of Dunn, Barron, Washburn and Burnett Counties.

On June 12, 1899, a deadly F5 tornado struck New Richmond. The tornado's damage path was wide and long. The tornado formed on the banks of the St. Croix River, south of Hudson. Moving to the northeast across St. Croix County, the tornado passed through the villages of Burkhardt and Boardman before striking New Richmond head on, leveling the entire business district and half the town's residences. The storm continued northeast, narrowly missing the town of Deer Park before crossing into Polk County, where it narrowly missed the towns of Clear Lake, Richardson, and Clayton. Once the tornado passed into Barron County, it struck the village of Arland before breaking up southwest of Barron. The tornado killed 117 people (four at Boardman, two in Polk County, and the rest at New Richmond), including at least 20 people who died from their injuries in the days after the storm. Largely thanks to state aid and donations, most of the town was rebuilt by the next winter. The tornado was the deadliest ever recorded in Wisconsin and the 9th deadliest tornado in U.S. history.
