The Planetary series of stories by Stanley G. Weinbaum is series of short stories, published in Wonder Stories and Astounding Stories in the 1930s, which are set upon various planets and moons of the Solar System.

The stories are marked by attention to the detail of the alien ecosystems with which Weinbaum equips his planets. Though only a few of the stories share protagonists, there is enough shared detail between the stories to show that they belong to a common fictional universe. The birdlike Martians of "A Martian Odyssey" and "Valley of Dreams", for instance, are mentioned in "Redemption Cairn", and "The Red Peri" and the Venusian trioptes of "Parasite Planet" and "The Lotus Eaters" are mentioned in "The Mad Moon". In Weinbaum's Solar System, in accordance with the then-current near-collision hypothesis, the gas giants radiate heat, enough to warm their satellites to Earthlike temperatures, allowing for Earthlike environments on Io, Europa, Titan, and even Uranus. Mars is also sufficiently Earthlike to allow humans to walk its surface (with training in thin-air chambers) unprotected.
