Shirley Hardie Jackson (December 14, 1916 – August 8, 1965) was an American writer, known primarily for her works of horror and mystery. Over the duration of her writing career, which spanned over two decades, she composed six novels, two memoirs, and more than 200 short stories.

Born in San Francisco, California, Jackson attended Syracuse University in New York, where she became involved with the university's literary magazine and met her future husband, Stanley Edgar Hyman. After they graduated, the couple moved to New York and began contributing to The New Yorker, with Jackson as a fiction writer and Hyman as a contributor to "Talk of the Town". The couple settled in North Bennington, Vermont, in 1945, after the birth of their first child, when Hyman joined the faculty of Bennington College.

After publishing her debut novel, The Road Through the Wall (1948), a semi-autobiographical account of her childhood in California, Jackson gained significant public attention for her short story "The Lottery", which presents the sinister underside of a bucolic American village. She continued to publish numerous short stories in literary journals and magazines throughout the 1950s, some of which were assembled and reissued in her 1953 memoir Life Among the Savages. In 1959, she published The Haunting of Hill House, a supernatural horror novel widely considered to be one of the best ghost stories ever written. Jackson's final work, the 1962 novel We Have Always Lived in the Castle, is a Gothic mystery which has been described as Jackson's masterpiece.

By the 1960s, Jackson's health began to deteriorate significantly, ultimately leading to her death due to a heart condition in 1965 at the age of 48.
