Kinosternon arizonense is an extinct species of mud turtle in the genus "Kinosternon". Initially described by Charles W. Gilmore in 1922. In 2016 McCord examined available Pliocene material of "K. arizonense" and concluded that the fossil material differs significantly from the extant turtles. Joyce and Bourque (2016) concurred. Rhodin et al. (2017), listed "Kinosternon arizonense" as extinct.
