Hennepin County ( /ˈhɛnəpɪn/ HEN-ə-pin) is a county in the U.S. state of Minnesota. As of the 2010 census the population was 1,152,425.  It is the most populous county in Minnesota and the 35th-most populous county in the United States; more than one in five Minnesotans live in Hennepin County. Its county seat is Minneapolis,  the state's most populous city. The county is named in honor of the 17th-century explorer Father Louis Hennepin. 
The center of population of Minnesota is in Hennepin County, in the city of Minneapolis.
Hennepin County was created in 1852 by the Minnesota Territorial Legislature. Father Louis Hennepin's name was chosen because he originally named St. Anthony Falls and recorded some of the earliest accounts of the area for the Western world. Hennepin County's early history is closely linked to the establishment of the cities of Minneapolis and St. Anthony.  The history of Hennepin County is cataloged at the Hennepin History Museum, located in Minneapolis.
According to the U.S. Census Bureau, the county has a total area of 607 square miles (1,570 km 2 ), of which 554 square miles (1,430 km 2 ) is land and 53 square miles (140 km 2 ) (8.7%) is water.  Hennepin is one of 17 Minnesota counties with more savanna soils than either prairie or forest soils, and is one of only two Minnesota counties with more than 75% of its area in savanna soils (the other is Wright County).
The highest waterfall on the Mississippi River, the Saint Anthony Falls (discovered by Louis Hennepin) is in Hennepin County next to downtown Minneapolis, but in the 19th century, the falls were converted to a series of dams. Barges and boats now pass through locks to move between the parts of the river above and below the dams.

In August 2006, the Board voted 4–3 to levy a 0.15% sales tax within the county to fund the majority of the cost of a baseball stadium for the Minnesota Twins. Legislation passed by the Minnesota Legislature in the waning hours of the 2005-2006 session, and signed by Governor Tim Pawlenty, authorized the county to levy the tax without a voter referendum. It also created the Minnesota Ballpark Authority which constructed and manages the stadium on behalf of the county. The tax will be in effect for 30 years, with clauses allowing it to be increased by the board of commissioners. The stadium, Target Field, opened in April 2010.
