Calvin Jung (born February 17, 1945) is an American actor.
Graduating from high school in New York, Jung attended Massanutten Military Academy in Virginia. He attended Hillsdale College in Michigan, and left his senior year to pursue acting back in New York. His first professional acting job was a commercial in Canada in 1970. His New York debut was off-Broadway at the American Place theater (The Chickencoop Chinaman) in 1971. In 1974 he appeared as Mr. Lee in the long-running "ancient Chinese secret" commercial for Calgon water softener, a role of which he says, "The fact that you had an Asian couple speak without accents was advanced for that time. Forget about stereotypes, just having Asians speak without accents was a major breakthrough."
In 1976 his Broadway debut was with The Phoenix Repertory Theater in the dramas "Memory of Two Mondays" and "They Knew What They Wanted". He notes that he was the first "cross-casted" actor in the company. Also on Broadway he worked with George C. Scott and Hector Elizondo in "Sly Fox". Among his many New York theater gigs were those at the Brooklyn Academy ("Dawn Song"), at the New York Public Theatre ("FOB"); he also helped found an Asian/Asian American repertory company and helped get it into the La Mama Experimental Theatre, where he was a resident member (1970–1972).
