The Kellogg Interchange complex is a freeway interchange in Southern California, connecting the San Bernardino (Interstate 10), Orange (State Route 57), and Chino Hills (State Route 71) freeways. The interchange is located at the boundary between the cities of San Dimas and Pomona about 25 miles (40 km) east of downtown Los Angeles. It is named for the nearby W. K. Kellogg Ranch, now home to Cal Poly Pomona.
