The Milwaukee Journal Sentinel is a daily morning broadsheet printed in Milwaukee, Wisconsin, USA. It is the primary newspaper in Milwaukee, the largest newspaper in Wisconsin and is distributed widely throughout the state. It is the namesake of its owner, Journal Communications, which is publicly traded on the New York Stock Exchange.

The Journal Sentinel was first printed on Sunday, April 2, 1995, the result of the consolidation of operations between the afternoon Milwaukee Journal and the morning Milwaukee Sentinel, which had been owned by the same company, Journal Communications, for more than thirty years. The new Journal Sentinel then became a seven-day morning paper.

In early 2003, the Milwaukee Journal Sentinel began printing operations at its new printing facility in West Milwaukee. In September 2006, the Journal Sentinel announced it had "signed a five-year agreement to print the national edition of USA Today for distribution in the northern and western suburbs of Chicago and the eastern half of Wisconsin."
