星花木兰（学名：Magnolia stellata），又名日本毛木兰，为木兰科木兰属的植物。分布于日本以及中国大陆的青岛、南京等地，目前已由人工引种栽培。

Magnolia stellata, sometimes called the star magnolia, is a slow-growing shrub or small tree native to Japan. It bears large, showy white or pink flowers in early spring, before its leaves open. This species is closely related to the Kobushi magnolia (Magnolia kobus), and is treated by many botanists as a variety or even a cultivar of that. However, Magnolia stellata was accepted as a distinct species in the 1998 monograph by Hunt.
