The name "Northeast" originally came from the city’s street-naming system. Streets suffixed “North,” “South,” “East,” and “West” are all located west of the Mississippi River, while streets east of the river are suffixed “Northeast” and “Southeast.” The dividing line between these two suffixes is East Hennepin Avenue. Under this scheme, Northeast does not include all of the Old Saint Anthony business district, as much of that area (which includes landmarks such as Nye’s Polonaise Room) is on the “Southeast” side of that street. The Northeast Minneapolis Chamber of Commerce only identifies with the northeast streets.
