List of features on the Moon

Several features cover the surface of the Moon. These are listed below.

Among many lunar features are several large valleys that have been given names. Most of these valleys are named after a nearby crater; see the list of craters on the Moon for more information.

This is a list of maria (singular mare) on the Moon. Lunar Maria are the large, dark, regions of the moon. They do not actually contain any water, however they are believed to have been formed from molten rock from the moon's mantle coming out onto the surface of the moon. It also includes the one oceanus and the features known by the names lacus, palus and sinus. The modern system of lunar nomenclature was introduced in 1651 by Riccioli. Riccioli's map of the moon was drawn by Francesco Maria Grimaldi, who has a crater named after him.

There was also a region on the Lunar farside that was briefly misidentified as a mare and named Mare Desiderii (Sea of Dreams). It is no longer recognized. Other former maria include:

A related set of features are the Lunar lacus (singular lacus, Latin for "lake"), which are smaller basaltic plains of similar origin:

A related set of features are the sinus (singular sinus, Latin for "bay") and paludes (singular palus, Latin for "marsh"):

Some sources also list a Palus Nebularum ("Marsh of Mists") at 38.0° N, 1.0° E. However the designation for this feature has not been officially recognized by the IAU.

These are isolated mountains or massifs.

Note that the heights listed below are not consistent across sources. In the 1960s, the US Army Mapping Service used elevation relative to 1,737,988 meters from the center of the Moon. In the 1970s, the US Defense Mapping Agency used 1,730,000 meters. The Clementine topographic data published in the 1990s uses 1,737,400 meters.
