Seneca sits in the Lost Creek valley, with the old Frisco Railroad line running through town; the creek flows on toward Grand Lake of the Cherokees in Oklahoma.

Seneca had 877 households at the 2010 census, when its population stood at 2,336.

The city covers about 2.56 square miles of land in the Ozarks foothills at roughly 850 feet above sea level.
