Castanopsis sieboldii is a species of flowering plant in the family Fagaceae.^[2]^[3] This evergreen tree is sometime referred to by the common names Itajii chinkapin or Itajii. It is native to Japan, including the Ryukyu Islands, and Korea.^[2]^[4]^[5]

This is a climax species that is commonly found in the Japanese temperate rainforest.^[6] Specimens are also present within the forest area of the Tokyo Imperial Palace.

Castanopsis sieboldii was once thought to be a subspecies of the similar Castanopsis cuspidata.
