Rita Karin (born Rita Karpinowicz; October 24, 1919 – September 10, 1993) was a Polish-born American actress best known for her role as Jackie Mason's mother on the 1989 TV series Chicken Soup. She also appeared as Meryl Streep's Brooklyn landlady who appears at the beginning of Sophie's Choice. Her voice can be heard singing children's songs from the camps in the Holocaust Museum in Washington, D.C.

The couple emigrated in 1948 to the United States, where she acted in the Yiddish theater in New York City. She and other actors read the works of Sholom Aleichem at the home of Bel Kaufman, Aleichem's granddaughter, each year on the anniversary of the writer's death.
