John Smeaton "Jack" Dodson[1] (May 16, 1931 – September 16, 1994) was an American television actor best remembered for the milquetoast character Howard Sprague on The Andy Griffith Show and its spin-off Mayberry R.F.D.

Dodson initially portrayed insurance agent Ed Jenkins in the "Lost and Found" episode of The Andy Griffith Show.

In 1967, Dodson appeared in the episode "A Mighty Hunter Before the Lord" of NBC's The Road West, which aired opposite The Andy Griffith Show.

Set in Washington, D.C., Dodson played Wayne Joplin, a slightly bumbling Democratic senator from an unspecified rural state.

In January 1979, Dodson played Bernie, a hard of hearing acquaintance of Mark (David Spielberg), in a comic scene set in a restaurant in One Day at a Time.
