Anoka County is the fourth-most-populous county in the U.S. state of Minnesota. As of the 2020 United States census, the population was 363,887. The county seat and namesake of the county is the city of Anoka, which is derived from the Dakota word anokatanhan meaning "on (or from) both sides," referring to its location on the banks of the Rum River. The largest city in the county is the city of Blaine, the thirteenth-largest city in Minnesota and the eighth-largest Twin Cities suburb.
Anoka County comprises the north portion of the Minneapolis-St. Paul-Bloomington, MN-WI Metropolitan Statistical Area, the largest metropolitan area in the state and the sixteenth-largest in the United States with about 3.64 million residents.
The county is bordered by the counties of Isanti on the north, Chisago and Washington on the east, Hennepin and Ramsey on the south, Sherburne on the west, and the Mississippi River on the southwest. The Rum River cuts through the county and was the site of many early European settlements. It was a common route to the Mille Lacs Lake, the spiritual homeland of the Ojibwe people. Father Louis Hennepin traveled the river in his first exploration of the region. The area became a center of fur trade and logging as French and French Canadian communities grew in the cities of Anoka and Centerville. Organized in 1857, the county's southern border eventually met Minneapolis and has become a predominantly suburban area following the construction of Interstate 35W. The county is home to local Twin Cities destinations such as the Heights Theater in Columbia Heights and Northtown Mall and the National Sports Center in Blaine.
History
Anoka County was organized by an act of the Minnesota Territorial Legislature on May 23, 1857, the year prior to Minnesota's admission to the Union. It was formed from parts of Ramsey County and Benton County; the Rum River previously divided the line between the two counties. The boundaries were mainly the same as they are now, except for a small part of the southeastern tip along the Mississippi River and at the south, formerly known as Manomin County. It was a small portion that connected to Ramsey and occupied one-third of the congressional township. It was then attached to Anoka County by constitutional amendment November 2, 1869. It became known as Fridley in 1879.
The first European descendants to explore what is now Anoka County were the Franciscan friar Louis Hennepin and his party. Fur traders soon began to settle in the area which is now Ramsey County. They settled on the Rum River and more people were attracted to the area. A community was created which is now called Anoka.
