Avocado Heights (pronunciation) is an unincorporated census-designated place (CDP) in the San Gabriel Valley of Los Angeles County, California, United States. It is almost entirely surrounded by the City of Industry with only a small strip of unincorporated Los Angeles County separating it from South El Monte. It is in close proximity to both the Pomona (SR-60) and San Gabriel (I-605) freeways. To the west is the San Gabriel River and the California Country Club. Avocado Heights is approximately 15 miles (24 km) from the downtown Los Angeles Civic Center. The population was 15,411 at the 2010 census, up from 15,148 at the 2000 census.

A significant portion of Avocado Heights remains equestrian and semi-rural, with many homes on lots of 0.5 acres 21,780 square feet (2,023 m) or more. The proximity of polluting industries in what became the City of Industry, as well as the Puente Hills Landfill, suppressed property values throughout the post-World War II era—discouraging the development that transformed most of the San Gabriel Valley into a relatively densely developed suburban area.

Avocado Heights is located at 34°2′19″N 118°0′16″W / 34.03861°N 118.00444°W / 34.03861; -118.00444 (34.038610, −118.004575), or about 1.7 miles (2.7 km) southeast of El Monte.

The primary thoroughfare is Don Julian Road, named for the nickname given to early Anglo settler William Workman by local Californios; his homestead lies on Don Julian Road just to the east in Industry. The community is served by Don Julian Elementary School, which is part of the Bassett Unified School District.

Avocado Heights is known for its private ranches with horse riding.

From the 1920s until the early 2000s, there was a tall, single white tower on 3rd Avenue and Starlight Lane.
