Randolph Roberts (born October 5, 1947), also known as Will Roberts, is an American actor best known for being the second actor (after Gavan O'Herlihy) to portray Richie Cunningham's older brother Chuck on two episodes of Happy Days.

Roberts played Chuck starting in season 2's first episode "Richie Moves Out" and ending with "Guess Who's Coming to Christmas".

Chuck was not seen again but was later mentioned in a few other episodes ending with "Fish and the Fins" later in the season.

After that, Chuck was written off the show completely with later episodes depicting the Cunningham family with only two children with Richie as the elder.

Roberts eventually sidelined his acting career and became an education supervisor for ITT Technical Institute in San Diego.
