Riverdale is a town in McLean County, North Dakota, United States. The population was 223 at the 2020 census. ^[3]

Riverdale was the largest of the construction camps that sprang up in 1946 to house workers building the Garrison Dam just to the west. After the dam was completed in 1953, residents of the other camps (including Dakota City and Big Bend) who decided to stay on relocated to Riverdale. It was operated by the federal government from its establishment until 1986, when it was turned over to the state of North Dakota with incorporation following shortly thereafter.
