Patty Williams is a fictional character from the American CBS soap opera The Young and the Restless. The character made her debut in 1980, and after a brief portrayal by Tammy Taylor, Lilibet Stern took over for three years, followed by Andrea Evans until 1984. The character was re-introduced by former head writer Maria Arena Bell twenty-five years later in 2009, with Stacy Haiduk taking over the role. She appeared sporadically for an additional three years. Much of Patty's history revolves around her romance with Jack Abbott (Peter Bergman), as well as her repeated mental health issues.
