"The Red Peri" is a science fiction novella by American writer Stanley G. Weinbaum, which first appeared in the November 1935 issue of Astounding Stories.

Sam Moskowitz has noted that Weinbaum planned to write a series of sequels to "The Red Peri" but died before he could do so.

A year later, Keene and astrophysicist Solomon Nestor are on board the Limbo, conducting a survey of cosmic radiation in the outer reaches of the Solar System for the Smithsonian Institution.

The next morning, Elza tells him that the Red Peri has allowed him the run of the base; he has no access to a spacesuit or the key to his ship.

The next morning, after Elza slips him the key, Keene arrives at the base's entrance to find the Red Peri being loaded with supplies.

Carrying her, Keene sprints a thousand feet in the frigid vacuum of Pluto to the Limbo, barely making it to the airlock.

When she wakes up, he explains that stories of humans exploding in a vacuum are a myth—human tissue is strong enough to withstand the body's internal pressure for several minutes.

"The Red Peri" was written only five years after the discovery of Pluto by Clyde Tombaugh, when the only things known about it were its orbit and the fact that its apparent magnitude was 14.90, too dim to be a gas giant.

Everett F. Bleiler reported that "the background is imaginative, but the romance is on the level of the shopgirl pulps, and the writing leaves much to be desired.
