The Civic Center neighborhood of Los Angeles, California, is the administrative core of the City of Los Angeles, County of Los Angeles, and a complex of city, county, state, and federal government offices, buildings, and courthouses. It is located on the site of the former business district of the city during the 1880s and 1890s, since mostly-demolished.

The late-Victorian-era Downtown of Los Angeles in 1880 was centered at the southern end of the Los Angeles Plaza area, and over the next two decades, it extended south and west along Main Street, Spring Street, and Broadway towards Third Street. Most of the 19th-century buildings no longer exist, surviving only in the Plaza area or south of Second Street. The rest were demolished to make way for the Civic Center district with City Hall, numerous courthouses, and other municipal, county, state and federal buildings, and Times Mirror Square. This article covers that area, between the Plaza, 3rd St., Los Angeles St., and Broadway, during the period 1880 through the period of demolition (1920s–1950s).
