The Montgomery County Courthouse is located in Red Oak, Iowa, United States.

An election was held in 1863 that moved the county seat to Red Oak, but confusion of some sort ensued.

When the county seat was moved to Red Oak the courthouse was put on sleds and thirty yoke of oxen pulled it through a blizzard.

After the decision to replace it passed, an Omaha contractor failed to satisfy the contract and left the building uncompleted with numerous unpaid bills.

The exterior of the building features an abundance of towers, turrets, finials, cresting, and a large polygonal bay.
