Pritchardia munroi is a member of the palm family (Araecaceae). It is a tree up to 4 to 5 meters tall with drooping leaves that are deeply divided into segments. It was discovered in 1920 by Joseph F. Rock on the island of Moloka`i in Hawai`i and named it after James Munro, manager of Moloka`i Ranch. The two remaining individuals on Moloka`i grow near the base of a small ravine in East Moloka`i above Kamalo and Kapuaoko`olau.

This species has been recorded only from a small area on the leeward side of East Molokai. Only one tree remains in the wild. There are additional individuals in cultivation. The plant and its habitat are threatened by alien plants, pigs, deer, and goats. Rats are known to eat the fruits of this species. Fire is a potential threat to the plant.
