Morris is a city in Grundy County, Illinois, United States. The population was 13,636 at the 2010 census.
Morris is home to the Dresden Nuclear Power Plant, which provides a substantial portion of the electricity supply for the Chicago metropolitan area. Included among the Dresden plant's reactors is the first commercial nuclear reactor, housed in a spherical concrete and steel shell; it has since been decommissioned, and two more modern reactors (of 1970s vintage) now generate its electricity.
Currently, Morris has one of the few prospering and historically intact downtowns in Illinois. Visitors and shoppers come a distance to enjoy the tranquil small town shopping atmosphere. In addition to the downtown, there are outlying businesses such as five motels, a theater, restaurants, a furniture store, two drug stores, boat sales, three grocery stores, hardware stores, banquet hall, and numerous retail stores and gift shops.
