Center Junction is an unincorporated village and census-designated place (CDP) in Jones County, Iowa, United States.

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.

The Chicago & NorthWestern discontinued service on the line in 1951[citation needed].
