The Dream of X is a novella by English writer William Hope Hodgson, an abridged version of his 1912 science fiction novel The Night Land.

At that time, copyright in the United States could not be obtained until a book was printed within the US, but Hodgson was unable to find an American publisher willing to accept his 200,000-word novel.

As an alternative, he condensed the narrative to 20,000 words and personally financed a US edition by publisher R. Harold Paget, thereby securing US copyright.

The abridgment was originally published as part of the chapbook collection Poems and the Dream of X in 1912 by R. Harold Paget.
