Asa "Ace" Harris (April 1, 1910, New York City – June 11, 1964, Chicago) was an American jazz pianist.
In 1937 Harris took over leadership of the Sunset Royal Serenaders, and recorded with them that same year; he remained with the group until 1939.
In 1940 Harris became Pianist for Bill Kenny & The Ink Spots replacing Bob Benson.
Harris can be heard playing Piano with The Ink Spots on many Top 10 Pop hits including "Whispering Grass", "Maybe", "We Three (My Echo, My Shadow and Me)", "Java Jive", "I'll Never Smile Again", "I'd Climb The Highest Mountain", "We'll Meet Again", "Do I Worry", "Until The Real Thing Comes Along", "I Don't Want To Set The World On Fire", "Someone's Rocking My Dreamboat", "It's A Sin To Tell A Lie" and more.
A compact disc of Harris's recordings spanning 1937–52 was released by Jazz Classics in 2004.
