Quercus × crenata is a tree in the family Fagaceae.

Its taxonomic status is uncertain, as sources vary how they treat it.

As of October 2024[update], Plants of the World Online treated Quercus × crenata as a synonym of Quercus × hispanica, and hence as a hybrid between the European trees Turkey oak (Quercus cerris) and cork oak (Quercus suber).

[1][2] A 2007 molecular phylogenetic study supported the hybrid origin of the taxon, but used the specific epithet crenata rather than hispanica.

[3] As of October 2024[update], the World Flora Online treated the taxon as a separate species, Quercus crenata,[4] a view also taken in a 2018 study, where it is considered to be endemic to the Italian peninsula.
