The Colfax Spring City Commercial Historic District is a nationally recognized historic district located in Colfax, Iowa, United States.

The historic district represents the growth during this time period.

After the health-related mineral water industry declined, Colfax expanded its farm-to-market economy in the late inter-war and post-World War II years.

The historic district covers Colfax's central business district, and includes civic buildings, churches, retail establishments, fraternal organizations, banks, automobile-related strictures, and two parks.

Most of the buildings are of masonry construction with the former Presbyterian Church parsonage, the only house in the district, built of wood.
