Ken Weatherwax was an actor best known for the role of Pugsley Addams on the 1960s' television comedy The Addams Family.

Born in Los Angeles in 1955, Weatherwax began acting at a young age and was just nine when he was cast as Pugsley, the son of Gomez and Morticia Addams, played by John Astin and Carolyn Jones, respectively. The show, a macabre comedy that aired from 1964-66, was based on characters created by cartoonist Charles Addams.

When The Addams Family ended, Weatherwax sought other acting work, and at 17 he joined the U.S. Army.

He later worked in behind-the-scenes production roles, and in 1977 he reprised the role of Pugsley in the TV production Halloween with the New Addams Family.
