Biography of X is a 2023 alternative history novel by American writer Catherine Lacey published by Farrar, Straus and Giroux.

The novel purports to be a 2005 biography of the musician and artist X, written by her widow, C.M. Lucca, as a response to an unauthorized and apparently inaccurate biography of her wife written after her death. The novel takes place in an alternate timeline in which the Southern states of the United States seceded in 1945 after building a wall segregating them from the rest of the country.
