Daddy-Long-Legs is a 1912 epistolary novel by the American writer Jean Webster. It follows the protagonist, Jerusha "Judy" Abbott, as she leaves an orphanage and is sent to college by a benefactor whom she has never seen.

Jean Webster (pseudonym for Alice Jane Chandler Webster, July 24, 1876 – June 11, 1916) was an American writer and author of many books including Daddy-Long-Legs and Dear Enemy. Her best-known books feature lively and likeable young female protagonists who come of age intellectually, morally, and socially, but with enough humor, snappy dialogue, and gently biting social commentary to make her books palatable and enjoyable to contemporary readers.
