Elizabeth Ann Sheridan was an American actress and dancer. While best known for her roles as Jerry's mother in Seinfeld and the nosy neighbor, Mrs. Ochmonek, on sitcom ALF, her decades-long career was extensive and included work on the stage and large and small screens.

While working as a dancer in New York City nightclubs, Sheridan met the then-unknown James Dean. She wrote a book, Dizzy & Jimmy: My Life with James Dean: A Love Story, chronicling their time together in the early 1950s. In it, she describes them as each other's first romantic love. "We had great times... We didn't want to be apart. We found a place and lived together... [before he really hit it big]."

Dean pursued work on the stage in New York City, with film roles in Hollywood soon to follow. Without sure footing or a serious plan, forging a future was not an option, thus bringing about the end of their relationship. "He was being hauled away into this career, and I couldn't follow him," she said in an interview.

Sheridan died on April 15, 2022, at her home in Manhattan, aged 93.
