Marthaniel "Marcus" Roberts (born August 7, 1963)[1] is an American jazz pianist, composer, arranger, bandleader, and teacher.

His style has been influenced more by Jelly Roll Morton and Fats Waller than McCoy Tyner and Bill Evans, with an emphasis on ragtime and stride piano rather than bebop.

BYU conferred upon Roberts the degree of Doctor of Civic Engagement Through Music, honoris causa, for his outstanding life and contributions to society and to the world.

In his address, Roberts said: "We need to take time to really see each person, especially those who don't look or act like us, because if we hold onto and build upon that thread that binds us together, our ties will become stronger, we'll develop more of a sense of communion and trust with each other".

As part of his address, Roberts performed a special piano musical arrangement of the gospel hymn "Just a Closer Walk with Thee".
