The Illinois Concert is a live jazz recording of a concert by Eric Dolphy, released in 1999 by Blue Note Records. The album was recorded on March 10, 1963, at the University of Illinois in Champaign, Illinois and features Dolphy with pianist Herbie Hancock, bassist Eddie Khan, and drummer J.C. Moses. (Hancock would go on to join Miles Davis' Quintet roughly two months later.) The quartet is joined by the University of Illinois Brass Ensemble for one track, and by the University of Illinois Big Band for the final track. The tape of the concert, which was recorded for radio broadcast, did not surface until 1999, when it was mentioned in a chat room and was eventually brought to the attention of Michael Cuscuna.
