Whites settled in the Owatonna area in 1853 around the Straight River. Most of the white settlers were Yankees from New England and Upstate New York. The community was named after the Straight River, which in the Dakota language is Wakpá Owóthaŋna. A popular, but apocryphal, story is that the town is named after "Princess Owatonna", the daughter of local Native American Chief Wabena who was supposedly healed by a nearby spring's magic waters, which were said to be rich in iron and sulfur. The earliest the Owatonna area was settled was in 1854. It was platted in September 1855, incorporated as a town on August 9, 1858, and as a city on February 23, 1865.
