Don Matheson (August 5, 1929 – June 29, 2014) was an American soldier and policeman who later became a television actor, perhaps best known for his continuing role in Irwin Allen's series Land of the Giants.

While serving in Korea, he was awarded the Bronze Star for valorous leadership and a Purple Heart[1] for injuries suffered in an explosion.

The same year, he appeared as a guest star in the episode "Deadly Amphibians" on the sci-fi TV show's 4th season Voyage to the Bottom of the Sea.

After working in a number of plays, television episodes and commercials, Matheson was signed to join the cast of the Land of the Giants.

In 1976, he played the role of wealthy industrialist, Cameron Faulker, who married Lesley Williams (Denise Alexander) on General Hospital.
