Rhaphidophora petrieana is a plant in the arum family Araceae that is only found in the Wet Tropics bioregion of northeastern Queensland, Australia.

Rhaphidophora petrieana is a semi-epiphytic, robust, herbaceous, root climber reaching about 20 m (66 ft) tall.

[6] The type specimen was collected by Bruce Gray in 1982 from a National Park reserve west of Innisfail.

[2] Rhaphidophora petrieana occurs in rainforest from Cape Tribulation south to about Innisfail, at altitudes from sea level to about 800 m (2,600 ft).

There has also been isolated collections from near Lockhart River, about 200 km (120 mi) north of Cape Tribulation.
