The surface of the Moon has many features, including mountains and valleys, craters, and maria—wide flat areas that look like seas from a distance but are probably solidified molten rock. Some of these features are listed.

Lunar maria (singular mare) are large, dark, regions of the Moon. They do not contain any water, but are believed to have been formed from molten rock from the Moon's mantle coming out onto the surface of the Moon. This list 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.^[1] Riccioli's map of the Moon was drawn by Francesco Maria Grimaldi, who has a crater named after him.^[2]

The large majority of these features are impact craters. The crater nomenclature is governed by the International Astronomical Union, and this list only includes features that are officially recognized by that scientific society.

The lunar craters are listed in the following subsections. Where a formation has associated satellite craters (smaller associated craters), these are detailed on the main crater description pages.

Several large lunar valleys have been given names. Most of them are named after a nearby crater; see the list of craters on the Moon for more information.

The heights of the isolated mountains or massifs listed here are not consistently reported 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.

This list is not comprehensive, and does not list the highest places on the Moon. Clementine data show a range of about 18,100 meters from lowest to highest point on the Moon. The highest point, located on the far side of the Moon, is approximately 6500 meters higher than Mons Huygens (usually listed as the tallest mountain).

Mountains are referred to using the Latin word mons (plural montes).

The Moon's surface exhibits many other geological features. In addition to mountains, valleys, and impact craters, the following surface features have received names in the Lunar nomenclature, many of them named after a nearby crater or mountain.

The listed diameter for these features is the longest dimension that contains the entire geological formation. The latitudes and longitudes are in selenographic coordinates.
