Protivin is a city in Chickasaw and Howard counties in the U.S. state of Iowa. The population was 317 at the 2000 census. Early settlers named the city after the Bohemian town of Protivín in what is now the south of the Czech Republic.
The first Czech settlers arrived around 1855 and established themselves because the landscape reminded them of their home region. The community was and is predominately Catholic and they built their own church in 1878 which was the town's first structure.
Protivin holds an annual weekend festival known as Czech Days each August where the town's Czech heritage is celebrated. The event draws people from throughout Howard and Chickasaw Counties.
