Marquette most commonly refers to two places in the United States:

  • Marquette University is in Milwaukee, Wisconsin, in the downtown/near‑downtown area of the city in the American Midwest.
  • Marquette, Michigan is a city on the south shore of Lake Superior in Michigan’s Upper Peninsula, known as a small Lake Superior harbor city.

If you’re asking about the university, it’s an urban Catholic Jesuit campus in central Milwaukee; if you mean the city, it’s a northern Michigan lakefront town.
