Noble County is located in the north central part of Oklahoma. As of the 2010 census, the population was 11,561. Its county seat is Perry. It was part of the Cherokee Outlet in Indian Territory until Oklahoma Territory was created in 1890, and the present county land was designated as County P. After the U. S. government opened the area to non-Indian settlement in 1893, it was renamed Noble County for John Willock Noble, then the United States Secretary of the Interior.
