Alsophila junghuhniana, synonym Cyathea junghuhniana,[1] is a species of tree fern native to southern and central Sumatra and western Java, where it grows in forest at an altitude of 1000–2000 m. The trunk of this species is erect and may be 2 m tall or more.

Sori are borne near the midvein of fertile pinnules and are protected by thin indusia.

[2] Large and Braggins (2004) note that A. junghuhniana has been confused with Alsophila crenulata (syn.

Cyathea raciborskii), "from which it differs in several characteristics, including larger pinnae".

[2] The specific epithet junghuhniana commemorates German botanist Friedrich Franz Wilhelm Junghuhn (1809-1864), who collected numerous plants on Java and Sumatra.
