This list of nearest terrestrial exoplanets contains known terrestrial ("rocky") exoplanets at a distance of up to 50 light-years from the Solar System, ordered by increasing distance. They are composed primarily of silicate rocks and/or metals. Within the Solar System, the terrestrial planets are the inner planets closest to the Sun.

There are ten terrestrial exoplanets in this list, two of whom probably lie inside the habitable zone.
