The Bohemia River is a 4.7-mile-long (7.6 km) tributary of the Elk River on the Delmarva Peninsula. It is located in Cecil County, Maryland, with its headwaters extending into New Castle County, Delaware. There are several small creeks on the northern shore, including Pooles Creek and Manor Creek. On the southern shore small creeks include Morgan Creek and Scotchman Creek. The Bohemia River was once known as the Oppoquimimi River, as it was known by Native Americans. The river was renamed by Augustine Herman after Bohemia, the country of his birth.
