Richard Arnold "Groove" Holmes (Camden, New Jersey, May 2, 1931 – St. Louis, Missouri, June 29, 1991) was an American jazz organist who performed in the hard bop and soul jazz genre. He is best known for his 1965 recording of "Misty", and is considered a precursor of acid jazz.

Holmes' first album, on Pacific Jazz with guest Ben Webster, was recorded in March 1961.
