Joseph Henry Roberts (February 2, 1871 – October 28, 1923) was an American comic actor who appeared in 16 of Buster Keaton's 19 silent short films of the 1920s.

[2] When Buster's apprenticeship with Roscoe "Fatty" Arbuckle came to an end and Keaton began making his own short films in 1920, he asked Roberts to join him.

Roberts played "Roaring Bill" Rivers in 1922's The Primitive Lover starring Keaton's sister-in-law Constance Talmadge and silent film actor Harrison Ford.

He also played a drill master in the Clyde Cook comedy The Misfit, released in March 1924, after Roberts' death.

[citation needed] When Keaton began making feature films in 1923, he apparently intended to keep working with Roberts.
