Kathryn Hays (born Kay Piper; July 26, 1934 – March 25, 2022) was an American actress, best known for her role as Kim Hughes on the CBS soap opera As the World Turns from 1972 to 2010.

Hays was born as Kay Piper in Princeton, Illinois, on July 26, 1934, the only child of Roger and Daisy (Hays) Piper. Her parents divorced shortly after her birth. Hays was raised by her mother, who was a bookkeeper and a banker, and her stepfather, salesman Arnold Gottlieb.^[1]

She grew up in Joliet.^[2][3] She took classes at Northwestern University, and worked as a model. In 1962, she changed her name to Kathryn Hays (using her mother's maiden name as her last name).^[1]

Hays' first marriage was to salesman Sidney Steinberg in 1957, with whom she had a daughter, Sherri.^[1] In 1966, Hays married actor Glenn Ford; the couple divorced in 1969.^[4] Her third husband was Wolfgang Lieschke, who was employed in the advertising industry.^[1]

Hays died on March 25, 2022.^[1][12][13] She had been living in an assisted living facility at the time of her death.^[1] Her daughter, Sherri Mancusi, participated in a November 2022 fan tribute on The Locher Room YouTube channel that honored Hays; in the interview, Mancusi said that Hays had had dementia in the years prior to her death.^[14] "Mom had dementia, that's what killed her and most people who have dementia are good at masking it," Mancusi said. "Mom was an Oscar contender, and she had people with her all day in her home and she was out in Illinois at that point. Having lived with an artist since the day I was born, I know something about artists and it's that they don't retire. She couldn't drive a car at that point or fix a meal or run her own life, but she could still do an interview, or do a show."
