List of maria on the Moon

This is a list of maria (large, dark, basaltic plains) on the Moon.

The modern system of lunar nomenclature was introduced in 1651 by Giovanni Battista Riccioli.

[1] Riccioli's map of the Moon was drawn by Francesco Maria Grimaldi, who has a crater named after him.

A related set of features are the sinus /ˈsaɪnəs/ (singular sinus, Latin for "bay")[b] and paludes /pəˈluːdiːz/ (singular palus /ˈpeɪləs/, Latin palūs, palūdēs "marsh").

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