The Brill Building is an office building at 1619 Broadway on 49th Street in the New York City borough of Manhattan, just north of Times Square and farther uptown from the historic musical Tin Pan Alley neighborhood. The Brill Building housed music industry offices and studios where some of the most popular American songs were written. It is considered to have been the center of the American music industry that dominated the pop charts in the early 1960s.

It was built in 1931 as the Alan E. Lefcourt Building, after the son of its builder Abraham E. Lefcourt, and designed by Victor Bark Jr. The building is 11 stories high and has about 175,000 square feet (16,300 m²) of rentable area.

The "Brill" name comes from Maurice Brill, a haberdasher who operated a store at street level and subsequently bought the building. The Brill Building was purchased by 1619 Broadway Realty LLC in June 2013 and subsequently renovated. A CVS Pharmacy opened on the building's first two floors in 2019.

Before World War II, the Brill Building became a center of activity for the popular music industry, especially music publishing and songwriting. Scores of music publishers had offices in the Brill Building. Once songs had been published, the publishers sent song pluggers to the popular bands and radio stations. These song pluggers would sing and/or play the song for the band leaders to encourage bands to play their music.^{[citation needed]}

During the ASCAP strike of 1941, many of the composers, authors and publishers turned to pseudonyms in order to have their songs played on the air.^{[citation needed]}
