Nancy Dussault (born June 30, 1936) is an American singer and actress.
Born in Pensacola, Florida, her parents were George Adrian, a naval officer and Sarah Isabel (née Seitz). She grew up as a "Navy junior". A former resident of Arlington, Virginia, she graduated from Washington-Lee High School (W-L) where she was an actress and singer in the W-L drama program under director Jack Jeglum and a choral singer in the nationally known Washington-Lee High School Choir and Madrigal Singers under director Florence Booker. She is an alumna of Northwestern University.
In 1962, Dussault stepped into the role of Maria in the Broadway production of The Sound of Music. She received a Tony Award nomination in 1961 for Best Featured Actress (Musical) for Do Re Mi and was nominated for her performance in Bajour (1965). Of her performance in Do Re Mi and later career, Bloom and Vlastnik wrote: "Confidently clowning alongside such pros as Phil Silvers and Nancy Walker...she never faded into the scenery. Equally comfortable as a pure soprano or a rangy high belter, her versatility was well captured on the...cast album...Well cast as a situation comedy wife, she spent much of the 1970s and 80s in California." Other stage shows included Quality Street in 1965 at the Bucks County Playhouse in Pennsylvania. She also appeared in the City Center Gilbert & Sullivan NYC Company, directed by Dorothy Raedler, with such Metropolitan Opera singers as Nico Castel, Muriel Costa-Greenspon, and Frank Poretta, Sr. Dussault took over as the Witch in Into the Woods on Broadway (1987–89).
