Robert Henry Wright (born Belfast, 15 July 1874) spent part of his adult life in New Zealand and appears to have stopped writing before serving in the First World War, which he survived. His date of death is not recorded; he is known to have been alive after 1920.

Of speculative interest among his several books is The Outer Darkness (1906). The novel begins after the protagonist's death: he is transported to another planet whose monarch judges his moral condition and assigns him to a metaphysical realm. Earth itself is treated as Hell and the monarch's kingdom as Heaven, while the protagonist is sent to a planetary-romance version of Purgatory called Kellecheura, where he becomes the queen's consort but misses his wife.

The book combines afterlife fantasy, planetary romance, Christian allegory and spiritual cosmology, and its importance lies in transforming Christian eschatology into a cosmic geography - anticipating the fantastical solar systems of writers such as C. S. Lewis and David Lindsay.
