Washington County, County administrative division in Southeast Iowa, United States.
Washington County spans across 571 square miles of land featuring nine incorporated cities, including the county seat of Washington and the communities of Kalona and Riverside.
Originally established as Slaughter County in 1838, the territory changed its name to Washington County in 1839 to honor the first president of the United States.
The county maintains several historical landmarks and organizes regular events that connect residents through agricultural traditions and community gatherings throughout the year.
Major transportation routes include U.S. Highway 218 and multiple Iowa state highways that connect the county's communities to surrounding metropolitan areas.
The English River and Skunk River flow through the county, creating natural corridors that supported early timber industries and continue to shape the regional geography.
