Olmsted County is a county in the U.S. state of Minnesota. As of the 2010 census, the population was 144,248, and has an estimated population of 158,293 as of 2019. Its county seat and largest city is Rochester.
Olmsted County is part of the Rochester Metropolitan Statistical Area.
The Wisconsin Territory was established by the federal government effective 3 July 1836, and existed until its eastern portion was granted statehood (as Wisconsin) in 1848. Therefore, the federal government set up the Minnesota Territory effective March 3, 1849. The newly organized territorial legislature created nine counties across the territory in October of that year. One of those original counties, Wabasha, had portions partitioned off in 1853 to create Fillmore and Rice counties. Then on 20 February 1855, portions of Rice, Wabasha, and Fillmore counties were partitioned off to create the present county, with Rochester (which was also platted that year) as county seat. The county name recognized David Olmsted (1822-1861), a member of the first territorial council and the first mayor of St. Paul.
The county boundaries have remained unchanged since 1855.
Olmsted County is drained by three rivers, all flowing to the Mississippi. The Zumbro River flows northward through the west central part of the county, into Wabasha County. The Whitewater flows northeast from the northeast part of the county into Winona County, and the Root flows east-southeastward through the lower part of the county into Fillmore County. The county terrain consists of low rolling hills, etched by drainage gullies and marked by occasional buttes. The available area is devoted to agriculture or is developed for other productive uses. The county terrain slopes to the east and north, and its highest point is a hill 7.5 miles (12 km) west of Stewartville, at 1,380' (421m) ASL. The county has a total area of 655 square miles (1,700 km2), of which 653 square miles (1,690 km2) is land and 1.5 square miles (3.9 km2) (0.2%) is water.
