Covina is a small city in Los Angeles County, California about 22 miles (35 km) east of downtown Los Angeles, in the San Gabriel Valley region. 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, making it the smallest city in area in the country.
Covina is often confused with West Covina which is actually larger in both area and population, located to its south and westside. Irwindale lies to the west, as well as the unincorporated area of Vincent, and the city of Baldwin Park. Azusa and Glendora are to the north, the unincorporated community of Charter Oak to the northeast, San Dimas to the east, the unincorporated areas of Ramona and Via Verde, and the city of Pomona to the southeast.
The city was founded in 1882 by Joseph Swift Phillips, on a 2,000 acre tract that was purchased from the John Edward Hollenbeck holdings. The City of Covina was named by a young engineer, Frederick Eaton, who was hired by Phillips to survey the area. Impressed by the way in which the valleys of the adjacent San Gabriel Mountains formed a natural cove around the vineyards that had been planted by the region's earlier pioneers, Eaton merged the words "cove" and "vine", and in 1885, created the name Covina for the new township.
