Search Visit Oklahoma

The Grand (Neosho) River rises in Kansas and flows southeasterly entering Oklahoma northwest of Miami and merges with the Spring River near Wyandotte eventually emptying into the Arkansas River near Fort Gibson. It is 450 miles long, of which the final 150 miles lie within the boundaries of Oklahoma.

The river was known to the First Nation, Native Americans, poulace as "Six Bulls" and to the white man in 1806 as the "Grand". The "Neosho River" tag was picked up sometime prior to 1820.
