Magnolia sieboldii, or Siebold's magnolia, also known as Korean mountain magnolia and Oyama magnolia, is native to east Asia in China, Japan, and Korea. It is a large deciduous shrub or small tree 5–10 m (16–33 ft) tall.

The flowers, unlike the spring flowering magnolias, open primarily in late spring and early summer, and continue intermittently afterwards.

Magnolia sieboldii is grown as an ornamental tree in gardens. It is one of the hardiest magnolias, successful in cultivation as far north as Arboretum Mustila in Finland.

Siebold's magnolia is the national flower of North Korea.
