Pine Island is a city in Goodhue and Olmsted counties in the U.S. state of Minnesota. Most of Pine Island is in Goodhue County, but a small part extends into Olmsted County, making that portion part of the Rochester metropolitan area. As of the 2020 census, the population was 3,769. Pine Island was platted in 1856, given its name from the Native American term "Wa-zu-wee-ta," which translates to Isle of Pines. It lies along the Middle Fork of the Zumbro River.
The community has a strong agricultural base, but has been transitioning over time into a bedroom community for nearby Rochester, which employs many local residents. It is also the site of Minnesota's first diverging diamond interchange. Pine River features a golf course and history center.
