Howard Greenfield was an American lyricist and songwriter, who for several years in the 1960s worked out of the famous Brill Building. He is best known for his successful songwriting collaborations, including one with Neil Sedaka from the late 1950s to the mid-1970s, and near-simultaneous songwriting partnerships with Jack Keller and Helen Miller throughout most of the 1960s.

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 further uptown from the historic musical Tin Pan Alley neighborhood. 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 approximately 175,000 square feet (16,300 m2) of rentable area.
