Malportas Pond is a salt-water pond on the north coast of Grand Cayman, Cayman Islands, near North Side village. It has an area of 44 or 52 hectares, and like the nearby Rock and Point ponds, it is an important area for breeding waterfowl. Local farmer Willie Ebanks introduced West Indian whistling-ducks on the pond in 1990, and it also has populations of heron, egrets, moorhens, and coots. It forms part of the Central Mangrove Wetland Important Bird Area, identified as such by BirdLife International because it supports populations of waterbirds.
