San Pedro featured a network of streetcars between 1903 and 1958. The establishment of the Port of Los Angeles in the early 1900s spurred the development of the nearby city, and electric streetcars provided local transit services for workers and later military personnel. Pacific Electric was the primary operator in the city.

San Pedro is a neighborhood located within the South Bay and Harbor region of the City of Los Angeles, California, United States. Formerly a separate city, it consolidated with Los Angeles in 1909. The Port of Los Angeles, a major international seaport, is partially located within San Pedro. The district has grown from being dominated by the fishing industry, to a working-class community within the city of Los Angeles, to an increasingly dense and diverse community.
