Lily Walsh is a fictional character from the CBS daytime soap opera, As the World Turns. Most notably played by Martha Byrne from May 1985 to September 29, 1989 and again from April 1993 to April 22, 2008, the character was originated in June 1984 by Lucy Deakins. Heather Rattray stepped into the role from December 1989 to January 8, 1993. In the show's final two years, Lily was recast with Noelle Beck and she aired from May 8, 2008 after the much-publicized departure of Byrne until its final episode on September 17, 2010. Byrne is considered to be one of the most recognized faces of daytime television and is often called a "superstar" of soap opera history.
