Flight to Opar is a fantasy novel by American writer Philip José Farmer, first published in paperback by DAW Books in June 1976, and reprinted twice through 1983. The first British edition was published by Magnum in 1977; it was reprinted by Methuen in 1983. It was later gathered together with a preceding novel, Hadon of Ancient Opar, and a sequel, The Song of Kwasin, into the omnibus collection Gods of Opar: Tales of Lost Khokarsa (2012). The work has also been translated into French. It and the other books in the series purport to fill in some of the ancient prehistory of the lost city of Opar, created by Edgar Rice Burroughs as a setting for his Tarzan series.
