Mount San Antonio, commonly referred to as Mount Baldy or Old Baldy, is a 10,064 ft (3,068 m) summit in the San Gabriel Mountains on the border of Los Angeles and San Bernardino counties of California.[4][5] Lying within the San Gabriel Mountains National Monument and Angeles National Forest, it is the highest point within the mountain range, the County of Los Angeles, and the Los Angeles metropolitan area.

Mount San Antonio's sometimes snow-capped peaks are visible on clear days and dominate the view of the Los Angeles Basin skyline. The peak and a subsidiary one to the west form a double summit of a steep-sided east–west ridge. The summit is accessible via a number of connecting ridges along hiking trails from the north, east, south, and southwest.
