American writer, remembered for her plays and for her humorous prose on domestic themes.

Jean Collins graduated from Marywood College in Scranton in 1943, and in August of that year she married Walter F. Kerr, who was then a professor of drama at Catholic University of America, Washington, D.C., and who later became drama critic for the New York Herald Tribune and The New York Times. She received an M.F.A. degree from Catholic University in 1945.

In March 1946 the Kerrs' collaborative adaptation of Franz Werfel's novel The Song of Bernadette was produced on Broadway. It was a commercial failure but a worthy apprentice piece. Jean Kerr alone wrote Jenny Kissed Me, which was produced in December 1948 with only slightly greater success. Touch and Go, for which the Kerrs wrote sketches and lyrics, ran for 176 performances from its opening in October 1949, and Jean Kerr's sketches in John Murray Anderson's Almanac in 1953–54 were highly praised. With Eleanor Brooke she wrote King of Hearts, a comedy directed by Walter Kerr that opened in April 1954 and ran for 279 performances. In 1957 she published a collection of comic sketches on domestic life under the title Please Don't Eat the Daisies. The book was a best-seller and was adapted as a popular motion picture and later a television series under the same title. The Snake Has All the Lines (1960) was in the same vein as the earlier book. Mary, Mary opened on Broadway in March 1961 and enjoyed a huge success, running for 1,572 performances. Kerr's next play, Finishing Touches, ran from February to July 1973. Her other works include the plays Poor Richard (1964) and Lunch Hour (1980). She also wrote Penny Candy (1970) and How I Got to Be Perfect (1978). Her last play, Lunch Hour, was staged in 1980.
