Hanapepe or Hanapēpē is a historic, unincorporated community in Kauai County, Hawaii, United States. The name means "crushed bay" in Hawaiian, which may refer to landslides in the area.

Hanapepe was one of the locations visited by the United States Exploring Expedition under Charles Wilkes; the expedition arrived in Hawaii in late September 1840 and spent some time in the islands.

It is one of the few towns on the island that was not created by the sugarcane plantations. In 1924, an armed labor dispute involving sugar workers occurred, ending in the Hanapepe massacre.

Hanapepe is located on the southern side of the island of Kauai. It is bordered to the east, across the Hanapēpē River and Hanapepe Bay, by the community of Eleele. Hawaii Route 50 passes through the southern part of Hanapepe, leading east 17 miles (27 km) to Lihue and northwest 6 miles (10 km) to Waimea.
