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.

In this continuation of Hadon's adventures in the ancient Africa of 12,000 years ago, the last-ditch defense of the High Priestess he and his allies mounted against the tyrannical King's evil schemes segues into a perilous chase through various exotic cities, seas and islands.

Hadon undertakes to take his mate, now pregnant with his child, to safety at his native city of Opar, but is pursued by members of a dark cult in the service of the king.

Hadon's beloved clearly appears destined to a crucial future role which is never quite reached.

He has stated that he intended to have Hadon's son emigrate to the south in the wake of the catastrophe that would ultimately destroy the Khokarsan civilization in which the series is set, there to found the city of Kor that would afterward become the setting of H. Rider Haggard's fantasy novel She.
