Rockford is a city in Wright and Hennepin counties in the U.S. state of Minnesota. The population was 4,316 at the 2010 census. While Rockford is mainly located within Wright County, a small part of the city extends into Hennepin County. It is part of the Minneapolis–Saint Paul metropolitan statistical area. Minnesota State Highway 55 serves as a main route in the city.

Evidence of indigenous settlement in what is today Rockford can be found in burial mounds ranging from 500 to 1500 years old, as well as a trail which runs under the Bridge Street Bridge on the Hennepin County side. The area was a natural border land between the Ojibwe and Dakota, with both tribes utilizing the space for hunting and wintering. Though the space was primarily utilized by the Dakota, there also existed an Objibwe village near modern-day Dayton, on the Crow River.

As colonial settlement widened in Wisconsin, the Ho-Chunk were pushed west and forced to resettle near Rockford. Though the creation of a reservation at the site was proposed, concerns were raised about the proximity of an indigenous reservation so close to Minneapolis, a rapidly-developing economic center at the time. After the Treaty Traverse de Sioux in 1851, the land was opened to white settlers; after surveying was completed in 1854, plots became available for purchase to homesteaders.

In 1855,  brothers-in-law George F. Ames and Joel Florida of Illinois came up the Crow River with carpenter Guildford D. George with hopes of starting a mill town. Eventually the town would boast multiple thriving mills: a lumber, a flour, and a saw mill. Four years later, in 1859, the first US troops called to Minnesota were dispatched to Rockford in response to the so-called Wright County War, a period of rioting in the area.

A stockade was built in town during the Dakota Uprising of 1862, and again in 1863.

Rockford was incorporated in 1881, with a railroad running through the town being completed in 1886.

According to the United States Census Bureau, the city has a total area of 2.67 square miles (6.92 km); 2.61 square miles (6.76 km) is land and 0.06 square miles (0.16 km) is water.

The Crow River is formed at Rockford by the confluence of its North and South Forks.
