Herbert Alonzo "Lon" McCallister Jr. (April 17, 1923 – June 11, 2005) was an American actor. According to one obituary, he was best known for "playing gentle, boyish young men from the country." Another said he "had an ingenuous appeal that made him a favourite of family audiences, and was particularly at home in outdoor settings featuring dogs and horses. Ultimately his perennial boyishness and slight stature became a handicap for more mature roles."
