The Lumber River is a 133-mile-long (214 km) river in south-central North Carolina in the flat Coastal Plain. European settlers first called the river Drowning Creek, which still is the name of its headwater. The waterway known as the Lumber River extends downstream from the Scotland County-Hoke County border to the North Carolina-South Carolina border. Soon after crossing into South Carolina, the Lumber River flows into the Little Pee Dee River, which flows into the Pee Dee River, or Great Pee Dee River.
