Cynipinae is a subfamily of gall wasps (Cynipidae).

[1] Many of the approximately 1,500 described species cause galls on oaks, but some induce galls on other plant species or are inquilines of the gall-inducing species.

[1][2] Species occur on all continents, except Antarctica, with most found in the temperate regions of the northern hemisphere.

[1] All extant cynipid species are within Cynipinae since the only other recognized subfamily is Hodiernocynipinae, which is based on the fossil genus Hodiernocynips.

[3] There are 9 tribes currently recognized within Cynipinae:[1]
