Kualapuʻu is a census-designated place on the island of Molokai in Maui County, Hawaiʻi, United States. The population was 2,027 at the 2010 census. Kualapuʻu can be literally translated as "hill overturned", but is thought to be a corruption of Puʻuʻuala: "sweet potato hill". The present settlement is a former pineapple cannery village once associated with Del Monte Foods.
