Stephanie Novacek (b. Iowa City, Iowa, 31 August 1970) is an American operatic mezzo-soprano who has appeared at many of the world's opera houses. A regular performer at the Houston Grand Opera and Opera Atelier, Novacek is especially known for her performances in contemporary operas and in obscure operas, particularly baroque works, outside of the standard repertory. Opera News has described her voice as a "rich, seamless flow of solid silk" and an actress "with always a strong presence on stage".
Novacek studied voice at the University of Illinois at Urbana-Champaign (M. Mus. 1995) and began her career in 1996 as a member of the Young Artist Programs at the Santa Fe Opera in New Mexico and the Houston Grand Opera (HGO) in Texas. She made her professional opera debut that year as The Page of Herodias in Richard Strauss's Salome with HGO and her career has largely been based with that company ever since. With Santa Fe Opera she appeared in productions of Stravinsky's The Rake's Progress, Puccini's Madama Butterfly, and the world premiere of Tobias Picker's Emmeline as a member of the chorus during the summer of 1996.
With HGO Novacek created the roles Maria Callas in Michael Daugherty's Jackie O in 1997 and Jo March in Mark Adamo's Little Women in 1998. Her role in the latter received particular praise from critic Matthew Gurewitsch of the New York Times stating, "In Stephanie Novacek's portrayal of Jo March, Mr. Adamo's heroine, a star was born." Novacek appears on CD recordings of both operas and her performance of Jo March was recorded for DVD and broadcast on PBS's Great Performances in 2001. Novacek's many other roles with HGO include Hänsel in Humperdinck's Hänsel und Gretel, Messaggera in Monteverdi's L'Orfeo, Marcellina in Mozart's Le nozze di Figaro, Siebel in Gounod's Faust, Maddalena in Verdi's Rigoletto, Olga in Tchaikovsky's Eugene Onegin, Suzuki in Puccini's Madama Butterfly and the title role in Bizet's Carmen among others.
