Bradbury is a city in the San Gabriel Valley region of Los Angeles County, California, United States.

It is located in the foothills of the San Gabriel Mountains below Angeles National Forest.

The city has three distinct areas—the Bradbury Estates, which is a gated community consisting of 5-acre (20,000 m2) minimum estates; Woodlyn Lane, which is also a gated community with minimum 2-acre (8,100 m2) lots; and the balance of the city, which is not gated, which has lots generally ranging in size from 7,500 square feet (700 m2) to 1-acre (4,000 m2).

After years of annexation attempts by the city of Monrovia, Bradbury incorporated in 1957.

Still, many ties between the two communities remain in that they both form the Duarte Unified School District; they both share the same post office and the 91008 ZIP code; and they both share combined public services such as the Los Angeles County Sheriff's Department and Los Angeles County Fire Department.

According to the United States Census Bureau, the city has a total area of 2.0 square miles (5.2 km2), over 99% of it land.

The racial makeup of Bradbury was 652 (62.2%) White (49.0% Non-Hispanic White),[25] 22 (2.1%) African American, 4 (0.4%) Native American, 276 (26.3%) Asian, 0 (0.0%) Pacific Islander, 59 (5.6%) from other races, and 35 (3.3%) from two or more races.

None of the families and 2.0% of the population were living below the poverty line, including no under eighteens and none of those over 64.

In the California State Legislature, Bradbury is in the 25th Senate District, represented by Democrat Sasha Renée Pérez, and in the 48th Assembly District, represented by Democrat Blanca Rubio.

The Los Angeles County Sheriff's Department (LASD) serves Bradbury through the operation of the Duarte satellite substation as well as the Temple Station in Temple City.
