Waipiro Bay is a small coastal settlement in the Gisborne District on the East Coast of the North Island of New Zealand. The name also refers to the bay that the settlement is built on. It was named Waipiro by Chief Paoa, which translates literally to "putrid water", referring to the area's sulphuric properties. It is in the Waiapu ward, along with nearby towns Te Puia Springs, Tokomaru Bay, and Ruatoria.
