Nina Webster is a fictional character from The Young and the Restless, an American soap opera on the CBS network, portrayed by Tricia Cast. She was introduced during the episode airing on June 26, 1986, as a pregnant teenager whom Christine Blair (Lauralee Bell) befriends. Cast remained a regular cast member for fifteen years before asking for a contract release and departing onscreen in February 2001. In 2008, the actress returned for several guest spots, and the following year, she returned for a bigger storyline, and has continued to make occasional appearances until 2014. Cast later returned in 2020 and 2021. Cast described Nina as "someone who is confused generally". After her child was stolen from her hands at birth, Nina was later involved in a romance with Phillip Chancellor III (Thom Bierdz), which resulted in another child, Phillip Chancellor IV (John Driscoll). Phillip III then died—which many years later proved to be faked—and Nina raised Phillip IV as a single mother. She became a novelist and screenwriter, also having marriages to David Kimble (Michael Corbett) and Ryan McNeil (Scott Reeves). Nina was also involved with a man named Tomas Del Cerro (Francesco Quinn), a publisher interested in a novel of hers about her stolen son. In 2010, Nina met her long lost son, revealed to be Ronan Malloy (Jeff Branson). In 1992, Cast won a Daytime Emmy Award for her portrayal.
