Richard Bernard Halligan (August 29, 1943 – January 18, 2022) was an American musician and composer, best known as a founding member of the jazz-rock band Blood, Sweat & Tears.
He received a Grammy Award for Best Instrumental Performance for "Variations on a Theme By Erik Satie" from the album Blood, Sweat & Tears.
Halligan also arranged many of the band's charts during this time period, and he wrote several songs including "Redemption" and "Lisa Listen to Me."
Halligan left BS&T in 1971 after recording their fourth album, when the band began to shift to more rock-oriented music.
