Dundas is a city in Rice County, Minnesota, United States. The population was 1,367 at the 2010 census.
Settled in the mid-1500s, the city was later founded in 1867 by the Archibalds: Brothers John Sidney and Edward T., along with their cousin George Archibald named it after their hometown of Dundas, Ontario, Canada. The brothers built mills on both sides of the Cannon River.
The ruins of The Archibald Mill a flour mill can still be seen today on the west bank of the Cannon River. The milling industry contributed greatly to Dundas' 19th-century success, and at one point the mills in Dundas were considered among the best in the world.
