Martin Vidnovic (born January 4, 1948) is an American actor and singer.
Born in Falls Church, Virginia, Vidnovic made his Broadway debut in the ill-fated Home Sweet Homer (1976) which, following a one-year tour, closed on opening night. He fared better with his next three projects, revivals of The King and I (1977), Oklahoma! (1979), and Brigadoon (1980).
Vidnovic's performance in Baby (1983) won him the Drama Desk Award for Outstanding Featured Actor in a Musical. Additional Broadway credits include Guys and Dolls (1992), A Grand Night for Singing (1993), and King David (1997). He was cast in the 1998 stage adaptation of Footloose but was replaced during previews.
Off-Broadway, Vidnovic was cast as El Gallo late in the run of the original production of The Fantasticks and appeared in the 2006 revival as Bellomy. Additional off-Broadway credits include Lies and Legends: The Musical Stories of Harry Chapin (1985), Olympus on My Mind (1986), and the 2003 Jerry Herman revue Showtune.
Vidnovic is the father of actress Laura Benanti. He is also the uncle of former Minor Threat bassist Steve Hansgen.
