Diamond Bar is a city in eastern Los Angeles County, California, United States. The population was 55,544 at the 2010 census, down from 56,287 at the 2000 census. It is named after the "diamond over a bar" branding iron registered in 1918 by ranch owner Frederick E. Lewis.

Located at the junction of the Pomona and Orange freeways, Diamond Bar is primarily residential with shopping centers interspersed throughout the city. The city features a public Los Angeles County golf course, the Diamond Bar Golf Club. Well suited for many types of business, Diamond Bar is within Los Angeles County, but conveniently located adjacent to three major Southern California market areas; Orange, Riverside, and San Bernardino counties.
