The Broadway Theater District in the Historic Core of Downtown Los Angeles is the first and largest historic theater district listed on the National Register of Historic Places (NRHP). With twelve movie palaces located along a six-block stretch of Broadway, it is the only large concentration of movie palaces left in the United States. The same six-block stretch of Broadway, and an adjacent section of Seventh Street, was also the city's retail hub for the first half of the twentieth century, lined with large and small department stores and specialty stores.

The Historic Core is a district within Downtown Los Angeles that includes the world's largest concentration of movie palaces, former large department stores, and office towers, all built chiefly between 1907 and 1931. Within it lie the Broadway Theater District and the Spring Street historic financial district, and in its west it overlaps with the Jewelry District and in its east with Skid Row.
