Portland Island is a small island off the southern tip of the Mahia Peninsula on the North Island of New Zealand. It is used for sheep farming.

The area of the island fluctuates rapidly between high and low tides due to a shelf of rocks surrounding the east, north and west coast of the island. During low tide the area of the island can grow up to 3 km², while during high tide it shrinks down to only 1.4 km². This makes access by boat to the island rather difficult, despite it being only a kilometer offshore.
