Middleton is a city in Dane County, Wisconsin, United States. It is a western suburb of the state capital, Madison but it was actually founded before Madison. It got its name from Middletown, Connecticut; the "w" being dropped was due to a paper work error made by long time historian Edward Kromrey (namesake of the local middle school). Middleton's motto is "The Good Neighbor City".
