Brooklyn Park is a suburban city on the west bank of the Mississippi River, upstream from downtown Minneapolis in northern Hennepin County. It is the sixth-largest city in the U.S. state of Minnesota. The population was 86,478 at the 2020 census. The city still has undeveloped land and farms, including the historic Eidem Homestead, a 1900s working farm that is a popular tourist attraction for families and school field trips. Brooklyn Park is considered both a second- and third-tier suburb of Minneapolis, because much of the land north of 85th Avenue was developed after 2000.
