Alvin D. Kersh is a fictional character in the Fox science fiction television series The X-Files, played by James Pickens Jr. He serves as a figure of authority within the series, first introduced as an Assistant Director of the Federal Bureau of Investigation, and is later promoted to the post of Deputy Director. Kersh acts as an antagonist who bureaucratically prevents Special Agents Fox Mulder, Dana Scully, John Doggett and Monica Reyes from investigating cases dealing with the paranormal, dubbed X-Files.
Kersh first appeared as a guest role in several episodes of the series' sixth season, returning as a recurring character in the eighth and ninth seasons. Kersh's creation was driven by a need to place pressure on the character of Walter Skinner. The character has been met with mixed to negative critical responses, although he was initially positively received before coming to be considered a "one-note" role as the series progressed. Pickens, as part of the series' ensemble cast, earned a Screen Actors Guild Award nomination for his work.
