"Ex Oblivione" is a prose poem by American horror fiction writer H. P. Lovecraft, written in late 1920 or early 1921 and first published in The United Amateur in March 1921, under the pseudonym Ward Phillips.

An H. P. Lovecraft Encyclopedia suggests that the theme of "Ex Oblivione"—that nothingness is preferable to life—was derived from Lovecraft's reading the philosopher Arthur Schopenhauer. Lovecraft expressed similar sentiments in non-fiction work at the time, writing in In Defense of Dagon, "There is nothing better than oblivion, since in oblivion there is no wish unfulfilled."
