Washington Square is a short novel by Henry James. Originally published in 1880, it is a structurally simple tragicomedy that recounts the conflict between a dull but sweet daughter and her brilliant, unemotional father.

Henry James, OM (15 April 1843-28 February 1916) was an American-British writer. He is regarded as one of the key figures of 19th-century literary realism. James contributed significantly to literary criticism, particularly in his insistence that writers be allowed the greatest possible freedom in presenting their view of the world. His imaginative use of point of view, interior monologue and possibly unreliable narrators in his own novels and tales brought a new depth and interest to narrative fiction. His theatrical work is thought to have profoundly influenced his later novels and tales.
