Gail Sheehy (born November 27, 1937 in Mamaroneck, New York) is an American writer and lecturer, most notable for her books on life and the life cycle. She is also a contributor to the magazine Vanity Fair.
Her fifth book, Passages, has been called "a road map of adult life". Several of her books continue the theme of passages through life's stages, including menopause and what she calls "Second Adulthood", including Pathfinders, Spirit of Survival, and Menopause: The Silent Passage. Her latest book, Sex and the Seasoned Woman, reveals a hidden cultural phenomenon: a surge of vitality in women's sex and love lives after age fifty. She has also authored a biography of Hillary Rodham Clinton titled Hillary's Choice. Her novel Middletown, America is being adapted as a TV miniseries.
Sheehy attended the University of Vermont where she was a member of Alpha Chi Omega sorority and received a graduate degree in journalism from Columbia University.
