Cowling Arboretum 880 acres (3.6 km²) is an arboretum adjacent to Carleton College in Northfield, Minnesota, on a natural border between prairie and forest habitat, and in part on the floodplain of the Cannon River. It is open to the public without fee.
The Arboretum was established by Donald J. Cowling and Harvey E. Stork in the 1920s for education, conservation, and recreation. It is a Minnesota State Game Refuge, with some 10 miles of trails, and displays both native and non-native trees and shrubs.
