The Journal of Julius Rodman, Being an Account of the First Passage Across the Rocky Mountains of North America Ever Achieved by Civilized Man is an unfinished serial novel by Edgar Allan Poe, published in 1840.

It is a fictionalised account of the first expedition across the Western Wilderness, crossing the Rocky Mountains. The journal chronicled a 1792 expedition led by Julius Rodman up the Missouri River to the Northwest. This 1792 expedition would have made Rodman the first European to cross the Rocky Mountains. The detailed journal chronicles events of the most surprising nature and recounts '[T]he unparalleled vicissitudes and adventures experienced by a handful of men in a country which, until then, had never been explored by "civilised man"'.

The first six instalments of this novel were published in the Burton’s Gentleman’s Magazine in 1839-40, when the author was a contributing editor of the journal. When Poe left his job in June 1840, he refused to continue the novel. Extracts of Poe’s work infamously appeared in 1839 Congress papers citing his account of the first passage across the Rockies by ‘civilised man’ as authentic. Proving to be one of Poe’s more elaborate hoaxes, this reaction illuminates the extent to which his literary realism and acute attention to detail strikes a convincing background to the hero’s travels.
