Seth Gilliam is an American actor.


Graduating from SUNY Purchase in 1990, Gilliam started an acting career. He has a number of recurring roles on several TV series, including The Cosby Show and Teen Wolf, but became best known for his role on The Wire; in 2008, Gilliam attracted attention for criticizing the way in which the show, despite its critical success, has been overlooked for Emmy nominations. He has also had a number of guest-star roles in other TV shows, including CSI: Miami, Nurse Jackie, Skins, The Good Wife, and Criminal Minds. He also starred in a number of movies, which include Starship Troopers and Courage Under Fire.
