Lorraine Hansberry, (born May 19, 1930, Chicago, Illinois, U.S.—died January 12, 1965, New York, New York), American playwright whose A Raisin in the Sun (1959) was the first drama by an African American woman to be produced on Broadway.

This groundbreaking play starred Sidney Poitier, Claudia McNeill, Ruby Dee and Diana Sands in the Broadway production which opened in 1959. Set on Chicago's South Side, the plot revolves around the divergent dreams and conflicts within three generations of the Younger family: son Walter Lee, his wife Ruth, his sister Beneatha, his son Travis and matriarch Lena, called Mama. When her deceased husband's insurance money comes through, Mama dreams of moving to a new home and a better neighborhood in Chicago. Walter Lee, a chauffeur, has other plans, however: buying a liquor store and being his own man. Beneatha dreams of medical school.

The tensions and prejudice they face form this seminal American drama. Sacrifice, trust and love among the Younger family and their heroic struggle to retain dignity in a harsh and changing world is a searing and timeless document of hope and inspiration. Winner of the NY Drama Critic's Award as Best Play of the Year, it has been hailed as a "pivotal play in the history of the American Black theatre." by Newsweek and "a milestone in the American Theatre."
