Quercus salicina is an oak species found in Japan, South Korea and Taiwan. It is placed in subgenus Cerris, section Cyclobalanopsis.^[1]

The larvae of the Japanese oakblue (Arhopala japonica), of Acrocercops vallata and Marumba sperchius feed on Q. salicina.

Stenophyllanin A, a tannin,^[2] and other quinic acid gallates^[3] can be found in Q. salicina. The triterpene friedelin can also be isolated from the leaves of the tree.^[4]
