Lorenz "Larry" Milton Hart (May 2, 1895 – November 22, 1943) was the lyricist half of the famed Broadway songwriting team Rodgers and Hart. Some of his more famous lyrics include, "Blue Moon", "Isn't It Romantic?", "Mountain Greenery", "The Lady Is a Tramp", "Manhattan", "Where or When", "Bewitched, Bothered, and Bewildered", "Falling in Love with Love", "I'll Tell The Man In The Street" and "My Funny Valentine".

Hart was born in Harlem, the older of two sons, to Jewish immigrant parents, Max M. and Frieda (Isenberg) Hart, of eastern Europe and German descent. A business promoter, his father sent Hart and his brother Teddy to private schools. (His brother Teddy Hart also went into theatre and became a musical comedy star. His wife Dorothy Hart wrote a biography of Lorenz Hart.)

Hart attended Columbia University School of Journalism for two years. A friend introduced him to Richard Rodgers, and the two joined forces to write songs for a series of amateur and student productions.
