The former Oskaloosa Post Office is a historic building located in Oskaloosa, Iowa, United States. Completed in 1902, the Italian Renaissance Revival structure is composed of brick with decorative details in limestone and terra cotta.[2] Plans in 2013 to convert the building into housing fell through.[3] In 2019, a restoration project was begun to shore up the building. It was listed on the National Register of Historic Places in 2020.[1]
