The Kreyenhagen Hills are a range of foothills of the Diablo Range in western Fresno County and Kings County California. The Kreyenhagen Hills form a long foothill belt in the soft formations between Reef Ridge and Kettleman Plain. They are divided into several groups each a few miles wide by streams crossing them at right angles. They meet with the steep face of Reef Ridge and are distinct from the mountains which begin there.
