Alnus sieboldiana (オオバヤシャブシ in Japanese) is an alder species found on the islands of Honshu, Shikoku, and Suwanosejima in Japan.^[2]

A. sieboldiana contains ellagitannins including alnusiin, tellimagrandin I, pedunculagin, casuarinin, casuariin and 2,3-O-(S)-hexahydroxydiphenoyl-D-glucose.^[3]

The Latin specific epithet sieboldiana refers to German physician and botanist Philipp Franz von Siebold (1796–1866).^[4]
