Rosati's Authentic Chicago Pizza, commonly known as Rosati's Pizza, is a U.S.-based casual dining franchise that focuses on Chicago-style pizza. Its headquarters are located in Warrenville, Illinois. The brand operates more than 200 outlets across the country, with a significant portion—over one-third—situated within Illinois. In 2018, the company achieved revenues surpassing $211 million. The enterprise traces its origins back to 1926 when Saverio Rosati established the first pizzeria on Chicago's west side. Although the initial site eventually closed, it was reopened in 1964 in Mount Prospect, Illinois. By 1995, the business had grown substantially under the leadership of Saverio’s five sons—Fred, Richard, Al, Bill, and Ronald—becoming the fourth-largest pizza chain in the Chicago metropolitan area, following Pizza Hut, Domino's, and Little Caesars. Rosati’s was ranked 21st in Pizza Today's 2018 list of the top 100 pizzerias and advanced into the top twenty by 2019 due to increased sales.
A familial disagreement led to the emergence of two separate restaurant chains both operating under the Rosati's name.
