The mountain is almost always referred to as Mount Baldy or Old Baldy by locals, to the point where many may not recognize the name Mount San Antonio. The mountain was named by a local rancher after Saint Anthony of Padua. When American settlers arrived and surveyed the land, Baldy - a reference to the bare fell-field of Baldy Bowl that dominates the south face visible from Los Angeles - became the predominant name, and it has stuck. Nonetheless, Mount San Antonio is the official name according to the GNIS, and is still used by a number of institutions (e.g. Mount San Antonio College).
