Peripentadenia phelpsii is a plant in the family Elaeocarpaceae which is endemic to a very small part of northeastern Queensland, Australia.

[4] It was formally described in a 1982 paper by Bernard Hyland and Mark James Elgar Coode, titled "A second species for the Australian genus Peripentadenia (Eleaocarpaceae)," and published in the Kew Bulletin.

[2][3] The type specimen is a collection made in 1976 by Bruce Gray,[2][4][5] a Queensland botanical collector and orchid specialist.

[7] The species was named in honour of Roy Phelps, who first collected fruit of the plant and brought them to the attention of the authors.

[4] The range of this tree is entirely restricted to the catchment area of the Mossman River, about 75 km (47 mi) north of Cairns, where it grows in mature rainforest at altitudes from 40 to 400 m (130 to 1,310 ft).
