Covina is a city in Los Angeles County, California, United States, about 22 miles (35 km) east of downtown Los Angeles, in the San Gabriel Valley. The population was 47,796 at the 2010 census, up from 46,837 at the 2000 census. The city's slogan, "One Mile Square and All There", was coined when the incorporated area of the city was only (some say slightly less than) one square mile.
Covina is bordered by West Covina, to its south and west side. Irwindale lies to the west, as well as the unincorporated area of Vincent, and the city of Baldwin Park. Azusa, Glendora, and the unincoporated community of Citrus are to the north, the unincorporated community of Charter Oak to the north-east, San Dimas to the east, and Walnut to the south-east.
Present-day Covina was originally within the homelands of the indigenous Tongva people for 5,000 to 8,000 years. In the 18th century it the became part of Rancho La Puente in Alta California, a 1770s Spanish colonial and 1842 Mexican land grants.
The city of Covina was founded in 1882 by Joseph Swift Phillips, on a 2,000-acre (8.1 km2) tract that was purchased from the holdings of John Edward Hollenbeck, one of the 1842 grantees of Rancho La Puente. In 1875 Hollenbeck had purchased a failed coffee plantation from three Costa Rican brothers, Pedro Maria Badilla, Julian Badilla, and Pedro Antonio Badilla; the latter purchased it from the heirs of Hollenbeck's 1842 co-grantee John A. Rowland.
