{{main|Quercus subg. Cerris|l1=''Quercus'' subg. ''Cerris''}}

The type species is ''Quercus cerris''.
* Sect. ''[[List of Quercus species#Section Cyclobalanopsis|Cyclobalanopsis]]'', the [[List of Quercus species#Section Cyclobalanopsis|ring-cupped oaks]] of eastern and southeastern Asia. These are evergreen trees growing {{convert|10|–|40|m|ft|0|abbr=off}} tall. They are distinct from subgenus ''Quercus'' in that they have acorns with distinctive cups bearing concrescent rings of scales; they commonly also have densely clustered acorns, though this does not apply to all of the species. Species of ''Cyclobalanopsis'' are common in the evergreen subtropical [[laurel forest]]s, which extend from southern Japan, southern Korea, and Taiwan across southern China and northern Indochina to the eastern Himalayas, in association with trees of the genus ''[[Castanopsis]]'' and the laurel family ([[Lauraceae]]).<ref name=DenkGrimManoDeng17/>
