Center Junction is an unincorporated village and census-designated place (CDP) in Jones County, Iowa, United States. The population was 111 at the 2010 census, at which time it was a city. It is part of the Cedar Rapids Metropolitan Statistical Area.
Center Junction was once an incorporated city, but following a special election that served as a referendum on the plan, the city council voted in 2015 to sell off its assets, disband, and turn administration over to the county. When the council took the action, then-Mayor Sandy Ricklefs cited the town's ailing finances as the primary reason for disbanding.
