The Colonia (or La Colonia) is a neighborhood (Spanish: barrio) located in the central portion of the city of Oxnard, California, USA. The neighborhood was laid out by the Colonia Land Improvement Company in close proximity of the sugar factory and beet fields to house workers just east of the city's downtown business district. Long a Latino barrio, it is home to lower-income families, César Chávez memorials and the popular La Colonia Youth Boxing Club, which has produced notable fighters such as Fernando Vargas, Roberto Garcia, Miguel Angel Garcia, Victor Ortíz, Brandon Rios and Mia St. John.
The north to south boundaries are Camino del Sol to 3rd Street and the west to east boundaries are Oxnard Boulevard (formerly state route 1) to Rose Avenue. While much of the northern boundaries are kept relatively pristine to border the recent newer housing developments, the western borders match the grit of the railroad tracks. The neighborhood contains one private and two public elementary schools. There is a small branch of the Oxnard Public Library in the northeast corner, where Internet access is free and there is a rich collection of books.
The area was part of the Chumash region, which extended from Point Conception to Santa Monica and back into the foothills as far as the Coast Range.
On May 22, 1837, the 44,883-acre (182 km2) Rancho El Rio de Santa Clara o la Colonia was granted to former Santa Barbara Presidio soldiers Valentin Cota, Leandro Gonzales, Rafael Gonzales, Salvador Valenzuela, Vicente Pico, Rafael Valdez and Vincent Feliz. The rancho, which was commonly spoken of, or was in the rancho days, as the Colonia, extended from the Santa Clara River south to the present day Point Mugu Naval Air Station, or to the boundary of Rancho Guadalasca, and east from the Pacific Ocean to the present day 101 Freeway, or to the boundary of Rancho Santa Clara del Norte.
