Young-Holt Unlimited (also known as Young-Holt Trio), were an U.S. soul and jazz instrumental musical ensemble from Chicago, Illinois.

Drummer Isaac "Red" Holt and bassist Eldee Young, formerly members of Ramsey Lewis' jazz trio, formed a new outfit called the Young-Holt Trio with pianist Don Walker in 1966. They met with modest success, including the minor hit with "Wack-Wack", which charted at number 40 on the Billboard Hot 100.
