Dundas (/ˈdʌndəs/ DUN-dəss)[7] is a city in Rice County, Minnesota, United States.

[9][10] The brothers named the city after their home Dundas County, Ontario, Canada.

The city's original central business district was located on Second Street, and by 1866 it included two general stores, a library, hotel, shoe store, restaurant, meeting hall and saloon.

All that remains of the original commercial district is the Ault Store (built in 1866), which started as a general store and housed the town's first library on the second floor; the same building also served as the home of the Dundas News for its operation from 1876 to 1879 when it was bought and absorbed by the Northfield News.

Today, the town is chiefly a bedroom community for nearby Northfield and the more distant Minneapolis-St. Paul metropolitan area.

The juxtaposition of Dundas and Northfield and their disparate zoning policies and attitudes toward development have led to some unusual growth patterns.

Dundas is home to a number of businesses, such as an off-sale liquor store and two bars that would be unable to get licenses to operate in Northfield.

In 1999, the threat of a Target store being sited in Dundas—rather than Northfield—was instrumental in forcing changes to Northfield's zoning to allow such uses.

According to the United States Census Bureau, the city has a total area of 1.92 square miles (4.97 km2), all land.

Minnesota State Highway 3 and Rice County Road 1 are two of the main routes in the community.
