The Flatrock River, also known as Flatrock Creek and other variants of the two names, is a 98-mile-long (158 km) tributary of the East Fork of the White River in east-central Indiana in the United States. Via the White, Wabash and Ohio rivers, it is part of the watershed of the Mississippi River, draining an area of 532 square miles (1,380 km2).The Flatrock River rises near Mooreland in northeastern Henry County, and flows generally southwestwardly through Rush, Decatur, Shelby and Bartholomew counties, past the communities of Lewisville, Rushville and St. Paul. It joins the Driftwood River at Columbus to form the East Fork of the White River. The New Hope Bridge and Pugh Ford Bridge span the river in Bartholomew County, Indiana.
