Susan Sheehan (née Sachsel; born August 24, 1937) is an American writer.

Born in Vienna, Austria, she won the Pulitzer Prize for General Non-Fiction in 1983 for her book Is There No Place on Earth for Me? The book details the experiences of a young New York woman diagnosed with schizophrenia. Portions of the book were published in The New Yorker, for which she has written frequently since 1961 as a staff writer. Her work as a contributing writer has also appeared in The New York Times and Architectural Digest.

In 1986, Sheehan published in The New Yorker “A Missing Plane,” a three-part series about the U.S. Army’s attempt to identify the remains of the victims of a 1944 airplane crash. In About Town: The New Yorker and the World It Made, Ben Yagoda called the article “exhaustive and ultimately exhausting.”
