Karen L. Hall is an American television writer best known for her work on the television series Judging Amy and M*A*S*H.
Hall was born in Chatham, Virginia. She is the daughter of Ervis Hall and Flo Hall, and is the sister of Barbara Hall. She graduated from Chatham High School in 1974 and from the College of William and Mary in 1978 with a BA in English. She was then awarded a fellowship from the Virginia Museum of Fine Arts to the University of Virginia, where she was in graduate school in the MFA Playwriting Program.
While at William and Mary, Hall took a three-week trip to Hollywood with students from the University of Richmond. There she attended writing seminars hosted by Earl Hamner and Alan Alda. Impressed by her talent, both Hamner and Alda kept in touch with her after she returned to Virginia. With their encouragement, she decided to move to California after graduating from the University of Virginia in 1979, and within a year she was story editor of Eight Is Enough and writing scripts for M*A*S*H. In her career as writer, producer and creative consultant, Hall has worked on numerous series including Hill Street Blues, Moonlighting, Roseanne and Grace Under Fire.
