Round Midnight" is a 1944 jazz standard by pianist Thelonious Monk. Jazz artists Cootie Williams, Dizzy Gillespie, Art Pepper, and Miles Davis have further embellished the song, with songwriter Bernie Hanighen adding lyrics. Both Williams and Hanighen have received co-credits for their contributions. It is thought that Monk originally composed the song sometime in 1940 or 1941. However, Harry Colomby claims that Monk may have written an early version around 1936 (at the age of 19) with the title "Grand Finale".
