'''Mare Ingenii''' {{IPAc-en|ɪ|n|'|dʒ|iː|n|i|aɪ}} (Latin ''ingeniī'', the "'''Sea of Cleverness'''") is one of the few [[lunar mare]] features on the [[Far side (Moon)|far side]] of the Moon. The mare sits in the Ingenii basin, which is of the [[Pre-Nectarian]] epoch, which lies in turn in the outer part of the older and much larger [[South Pole–Aitken basin]]. The mare material located in Ingenii and the surrounding craters is of the [[Upper Imbrian]] epoch. The dark circular feature which dominates this mare is the crater [[Thomson (crater)|Thomson]] (112&nbsp;km diameter), with the overflow from Ingenii/Thomson directly to the east. Mare Ingenii is incompletely and thinly covered over much of its expanse with mare lava sheets. The light grey crater to the south of Mare Ingenii is [[Obruchev (crater)|Obruchev]].

The mare has swirling patterns of bright material, similar to [[Reiner Gamma]] and to patterns within [[Mare Marginis]], which are not associated with topographic or volcanic features. The [[lunar swirls]] are believed to be associated with magnetic fields.<ref>{{cite book | first1=Motomaro | last1=Shirao | first2=Charles A. | last2=Wood | date=January 18, 2011 | title=The [[SELENE|Kaguya]] Lunar Atlas: The Moon in High Resolution | publisher=Springer Publications | isbn=9781441972859 }} Plate 91: Mare Ingenii</ref>

Prior to formal naming in 1961 by the [[International Astronomical Union|IAU]],<ref name=USGS/> the crater was known as ''Basin XIV''.<ref>{{Cite web|url=http://www.lpi.usra.edu/resources/mapcatalog/LunarFarsideCharts/LFC-1%201stEd/LFC-1%202ndEd/LFC-1A/|title=Lunar Farside Chart (LFC-1A)}}</ref>

Mare Ingenii is located at the [[Antipodal point|antipode]] of the [[Mare Imbrium]] impact basin.  The furrowed crater walls of the basin (and possibly those of [[Van de Graaff (crater)|Van de Graaff]] crater) may have been caused by focused seismic waves resulting from the Imbrium impact.<ref>{{cite journal | title=Seismic effects from major basin formations on the moon and mercury | last1=Schultz | first1=P.

The mare contains the second instance of a [[Geology of the Moon#Lunar lava tubes|lunar pit]] discovered on the Moon and one of several outside the Earth to date.<ref>{{cite web | url=http://www.universetoday.com/2010/06/17/very-clever-lro-views-huge-lava-tube-skylight-in-mare-ingenii/ | title=LRO Views Huge Lava Tube Skylight in Mare Ingenii | website=universetoday.com | date=June 17, 2010 | first=Nancy | last=Atkinson | access-date=2021-05-13 }}</ref>
