Orphan Star (1977) is a science fiction novel by American writer Alan Dean Foster.

Flinx, no longer a poor orphan, is chasing a merchant to Hivehom and Terra in search of information about his parentage.

Along the way Flinx is joined by Sylzenzuzex, a female Thranx member of the Commonwealth Church.

His chase leads him to Ulru-Ujurr, a planet under Edict from the United Church, ostensibly because it contains a highly intelligent telepathic race.

It is on Ulru-Ujurr that he discovers the mystery of his parentage and jump-starts the childlike Ulru-Ujurrians on their "Game of Civilization".
