The Eleven Point River is a 138-mile-long (222 km) river in southern Missouri and northern Arkansas, United States. It originates near Willow Springs, Missouri. It more than doubles in flow when Greer Spring Branch runs into it, adding over 200 million US gallons (760,000 m3) of water per day to the river. The name derives from the Mississippi Valley French word pointe, which is a wooded point of land marking a river bend. Voyageurs marked distance by counting these points of land or river bends. The river flows into the Spring River southwest of Pocahontas near the small town of Black Rock.
