La Iglesia de Nuestra Señora la Reina de los Ángeles is a historic Catholic church in Los Angeles, California, located on the historic Plaza de Los Ángeles near Downtown Los Angeles. Part of the larger El Pueblo de los Ángeles Historical Monument, the church's origins date to 1784, when the Spanish founded the Nuestra Señora Reina de los Ángeles Asistencia to support nearby Mission San Gabriel Arcángel. By 1814, the asistencia had been abandoned and a new church was founded in its place by Padre Luis Gil y Taboada. The church is one of the oldest buildings in Los Angeles.

Los Angeles Plaza or Plaza de Los Ángeles is located in Los Angeles, California. It is the central point of the Los Angeles Plaza Historic District. When Spanish Governor Felipe de Neve founded the Pueblo de Los Ángeles, his first act was to locate a plaza for the geographical center from which his town should radiate. De Neve's plaza was rectangular in form—75 varas wide by 100 in length. It was located north of the church; its southerly line very nearly coincided with the northerly line of West Marchessault street. On this, the cuartel, the public granary, the government house and the capilla (chapel), fronted.
