Terraforming (literally, "Earth-shaping") of a planet, moon, or other body is the hypothetical process of deliberately modifying its atmosphere, temperature, surface topography or ecology to be similar to those of Earth to make it habitable by humans.

The term is sometimes used more generally as a synonym for planetary engineering. The concept of terraforming developed from both science fiction and actual science. The term was coined by Jack Williamson in a science-fiction story ("Collision Orbit") published during 1942 in Astounding Science Fiction,

Based on experiences with Earth, the environment of a planet can be altered deliberately: however the feasibility of creating an unconstrained planetary biosphere that mimics Earth on another planet has yet to be verified. Mars is considered by many to be the most likely candidate for terraformation.

The process of transforming the Martian atmosphere to create a more habitable living environment is called terraforming.
