Quercus × hispanica, commonly known as Spanish oak, is tree in the family Fagaceae.

The taxon was first described as the species Quercus hispanica by Jean-Baptiste Lamarck in 1785.

As of October 2024[update], Plants of the World Online treated it as the hybrid between the European species Quercus cerris (Turkey oak) and Quercus suber (cork oak) using the hybrid name Quercus × hispanica.

[1] In this treatment, one of its many synonyms is Quercus × crenata, which may also be treated as a separate species.

[3] The Lucombe oak cultivar is frequently found in British collections.
