The '''Mayoan''' ({{langx|es|Mayoense}}) age is a period of [[geologic time]] from 11.8 to 10 [[Mya (unit)|Ma]], within the [[Miocene|Middle to Late Miocene]] epoch of the [[Neogene]], used more specifically within the [[South American land mammal age|SALMA classification]] in South America. It follows the [[Laventan]] and precedes the [[Chasicoan]] age.<ref>[https://paleodb.org/cgi-bin/bridge.pl?action=displayInterval&interval_no=725 Paleo Database: Mayoan]</ref>

== Etymology ==
The age is named after the [[Río Mayo Formation]] in the [[Golfo San Jorge Basin]] of [[Patagonia]], Argentina.
