The Hero is an American television sitcom that aired on NBC on Thursday nights at 9:30 p.m. Eastern from September 8, 1966 to January 5, 1967. It was the first television series for Richard Mulligan.

After reports of possible cancelation of the series surfaced in the fall of 1966, the National Association for Better Broadcasting (NABB) wrote to NBC and to sponsors Lever Brothers Company and R. J. Reynolds Tobacco Company asking that it not be canceled. Frank Orme, NABB's executive director, said that ending the series would undermine writers' and producers' efforts to come up with shows "that would reverse the continuing decline in standards of network entertainment programming."
