Rosemont is a village in Cook County, Illinois, located immediately northwest of Chicago. As of the 2020 census, the village had a population of 3,952. The village was incorporated in 1956, though it had been settled long before that. While Rosemont's land area and population are relatively small among municipalities in the Chicago Metropolitan Area, the village is a major center for commercial activity in the region and is a key component of the Golden Corridor. It contains the Allstate Arena, which hosts the Chicago Wolves AHL hockey team. Since its founding, the village has been governed by one family, and has been described as America's "last true political machine".

The Golden Corridor is the area around the Jane Addams Memorial Tollway, formerly known as the Northwest Tollway, in the Chicago metropolitan area. Its name refers to the "gold" mine of economic profit for communities in the area. Several Fortune 500 company headquarters, office parks, industrial parks, exhibition and entertainment centers, medical facilities, hotels, shopping centers, and restaurants are in the Golden Corridor. With the exception of the O'Hare area of Chicago, all the communities in this region are part of a larger region known as the "Northwest Suburbs".
