The White Mountains of Arizona are a small mountain range in the eastern part of the state, near the border with New Mexico. It is a part of the high country that extends through the middle of the state, the Mogollon Rim being adjacent to the west. Nearby communities include Show Low, Pinetop-Lakeside, and Eagar. Much of the range is within the Fort Apache Indian Reservation.
The highest summit is Baldy Peak, with an elevation of 11,490 ft (3,476 m) making it the second-highest point in Arizona, after Humphrey's Peak.
The mountains are drained to the south by several tributaries of the Salt River, and to the north by the Little Colorado River. There are several small lakes.
The part of the White Mountains outside the reservation is in the Apache-Sitgreaves National Forest.
