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. " In July 2007, CNN/Money and Money magazine considered Middleton the best place to live in the United States.
