Pico Rivera is a city located in southeastern Los Angeles County, California. The city is situated nearly 11 miles (18 km) southeast of downtown Los Angeles, on the eastern edge of the Los Angeles basin, and on the southern edge of the area known as the San Gabriel Valley. As of the 2020 United States census, the city has a population of 62,088. Pico Rivera is bordered by Montebello to the west, Downey to the south, Santa Fe Springs to the southeast, and Whittier to the east.

Pico Rivera was founded in 1958, from the union of the long-standing unincorporated communities of Pico (named for Pío Pico, the last Mexican executive of California) and Rivera (the Spanish word for “riverbank”). Situated upon a wealthy alluvial plain amongst the Rio Hondo and the San Gabriel River, the area was taking into account predominantly agricultural; but, at the terminate of WWII, the quick rising demand for homes lured builders to the attractive terrain. Since the 1950s, it has been both residential as capably as industrial. It had a Ford Motor Company forest for many years: Los Angeles Assembly. Pico Rivera lies below the Whittier Narrows, making it one of the “Gateway Cities”.

In January 1958, 56 percent of the electorate voted for incorporation. They approved a Council-Manager form of government, and the name “Pico Rivera” was normal for the new city. Five citizens were chosen from a slate of 24 candidates to promote as members of the first City Council; Pico Rivera officially became the 61st city in Los Angeles County.

The north side of the city is home to the Pico Rivera Sports Arena, where concerts and other happenings are held.
