A crater of eternal darkness is a depression on a body in the Solar System within which lies a point that is always in darkness. Such a crater must be located at high latitude (close to a pole) and be on a body with very small axial tilt.

The Moon's Shackleton Crater, as imaged by Earth-based radar, is one such crater.

Craters of eternal darkness might be advantageous for space exploration and colonization, as they could potentially preserve sources of water ice.
