Terry Castle (born October 18, 1953) is an American literary scholar. Once described by Susan Sontag as "the most expressive, most enlightening literary critic at large today," she has published eight books, including the anthology The Literature of Lesbianism, which won the Lambda Literary Editor's Choice Award. She writes on topics ranging from 18th-century ghost stories to World War I-era lesbianism to the so-called "photographic fringe."
The daughter of British parents, Castle was born in San Diego and lived in England and southern California as a child. She attended the University of Puget Sound and graduated in 1975 with a B.A. in English. She went on to attend the University of Minnesota to get her Ph.D. in English.
Starting around 2000, Castle increasingly began to write more widely and on personal topics beyond her academic career, writing that "having labored in the dusty groves of academe for over twenty years, I felt—as a new millennium unfolded—a desire to write more directly and personally than had previously been the case." Her essays appear frequently in the London Review of Books, the Atlantic, and the New Republic.
