Howard "Howie" Greenfield (March 15, 1936 – March 4, 1986) 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 a near-simultaneous (and equally successful) songwriting partnership with
Jack Keller throughout most of the 1960s.
