Peristylus biermannianus is a species of flowering plant in the family Orchidaceae, native to Nepal and the eastern Himalayas.

[1] The species was first described in 1895 as Habenaria biermanniana.

It was later transferred to Platanthera.

[1] A molecular phylogenetic study in 2014 found that Platanthera biermanniana was deeply embedded inside a clade otherwise consisting of species of Peristylus.
