Carmen Joan Duncan (7 July 1942 – 3 February 2019) was an Australian-born stage and screen actress and activist, with a career locally and internationally in the United States that spanned over 50 years.

Her television roles included the series Hunter (1967)[4] and she appeared in the evening soap opera Number 96 playing Helen Sheridan in 1973.

She later had an ongoing role in Skyways,[4] and guest starred in several episodes of A Country Practice as Terence Elliott's wife, Rowena.

Many of her critics, including TV Guide's Michael Logan, remarked that her accent sounded less American than her counterparts, making her seem out of place in the serial.

[2] Duncan retired from acting in 2006 and became a fundraising manager for the GO Fund, a New South Wales charity associated with gynaecological cancer.
