History
Founded in 1895
An old deed may name a county that no longer exists, or a boundary that has since moved.
County K, which became Kay, was created in Oklahoma Territory from part of the Cherokee Outlet and the Tonkawa Indian Reservation in Oklahoma Territory. In 1904 Kay County gained area from non-county land in Oklahoma Territory that included the Kaw Indian Reservation and part of the Ponca Indian Reservation. The county took its name from the letter K. Kay County became a county in the state of Oklahoma in 1907.
