Corona (Spanish for ''Crown'') is a city in Riverside County, California, United States. As of the 2010 census, the city had a population of 152,374, up from 124,966 at the 2000 census. The cities of Norco and Riverside lie to the north and northeast, Chino Hills and Yorba Linda to the northwest, and the Cleveland National Forest and the Santa Ana Mountains to the southwest, and unincorporated Riverside County along the rest of the border, respectively. Corona is approximately 48 miles (77 kilometers) southeast of Los Angeles and 95 miles (153 km) north-northwest of San Diego.
Corona, located along the western edge of Southern California's Inland Empire region, is known as the "Circle City" due to Grand Boulevard's 3 mi (4.8 km) circular layout. It is one of the most residential cities in the Inland Empire, but also has a large industrial portion on the northern half, being the headquarters of companies such as Fender Musical Instruments Corporation, Monster Beverage Corporation, and supercar manufacturer Saleen.
Corona, originally named South Riverside, was founded at the height of the Southern California citrus boom in 1886, and is situated at the upper end of the Santa Ana River Canyon, a significant pass through the Santa Ana Mountains. The town of Corona was once the "Lemon Capital of the World". A museum there presents the lemon's former role in the local economy. The city derived its name (and its nickname, "The Circle City") from the unique layout of its streets, with a standard grid enclosed by the circular Grand Boulevard, 2.75 miles (4.43 kilometers) in circumference.
