Carmen Duncan (born July 7, 1942 in Cooma, New South Wales) is an Australian actress. Carmen's younger sister is actor Paula Duncan.
Carmen Duncan is known to Australian audiences as a character actress in films and on television. Australian television roles included several episodes of the Australian series Hunter (1967) and she appeared for several months in evening soap opera Number 96 playing Helen Sheridan in 1973. From there, a role on the soap Certain Women followed. She later had an on-going role in Skyways, and guest starred in several episodes of A Country Practice as Rowena Elliott.
She later emigrated to the United States where she acted on television. From October 1988 to September 1994, she portrayed Iris Cory Wheeler on daytime soap opera Another World. She succeeded Beverlee McKinsey in the role after a long absence. Many of Duncan's 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. As an actress in Australia, Duncan was trained in the Cultivated Australian English dialect, which is often mistaken for a British accent.
After leaving the Another World role in the mid-1990s, Duncan returned to Australia, where she acted in bit parts on television series and lampooning her former soap opera image on television commercials. In 2003, she appeared as Anna on CrashBurn. In 2004, Duncan returned to the United States to fill in for Eileen Fulton as Lisa Grimaldi in three episodes of As the World Turns while Fulton was on emergency medical leave. Duncan continues to take permanent residence in Australia.
