Knox County is a county in the U.S. state of Nebraska. As of the 2010 census, the population was 8,701.[1] Its county seat is Center.[2] Knox County was named after Continental and U.S. Army Major General Henry Knox.[3][4]

In the Nebraska license plate system, Knox County is represented by the prefix 12 (it had the 12th-largest number of vehicles registered in the county when the license plate system was established in 1922).


Knox County was organized by the Territorial Legislature in 1857, and named L'Eau Qui Court, that being the French name for the river named by the Indians Niobrara--both names meaning, in English, Running Water. The name was changed to Knox by a statute passed February 21, 1873, which took effect April 1, 1873.[5][6]
