Guillaume made several guest appearances on sitcoms, including Good Times, The Jeffersons, Sanford and Son, Saved By The Bell: The College Years and in the 1990s sitcoms The Fresh Prince of Bel-Air and A Different World. His series-regular debut was on the ABC series Soap, playing Benson Dubois, a butler, from 1977 to 1979. Guillaume continued the role in a spin-off series, Benson, from 1979 until 1986. Guillaume also played Dr. Franklin in season 6, episode 8 (“Chain Letter”) of the series All in the Family, which he coyly referenced Marcus Welby, M.D., a TV series in which he had guest-starred in 1970.
In 1985, Guillaume appeared in the television mini-series North and South as abolitionist leader Fredrick Douglass, who escaped from slavery and became a leader of the anti-slavery movement prior to the American Civil War.
He also appeared as marriage counselor Edward Sawyer on The Robert Guillaume Show (1989), Detective Bob Ballard on Pacific Station (1991–1992), and television executive Isaac Jaffe on Aaron Sorkin’s short-lived but critically acclaimed Sports Night (1998–2000)] Guillaume suffered a mild stroke on January 14, 1999, while filming an episode of the latter series. He recovered and his character was later also depicted as having had a stroke. He also made a guest appearance on 8 Simple Rules for Dating My Teenage Daughter.
