Hoopers Inlet, Coastal inlet in Otago Peninsula, New Zealand.

Hoopers Inlet is one of two large inlets on the Pacific coast of the Otago Peninsula, 15 km east of central Dunedin and 2 km south of Portobello. It is shallow, turning mostly to sand and mud flats at low tide, and its mouth is narrowed by a large spit whose seaward side forms Allans Beach. Behind the beach lie wetland and swamp.

The name's origin is uncertain: an early settler family called Hooper lived nearby, yet the name appears on charts made before their arrival. A. W. Reed suggested it is a corruption of "Cooper's Inlet", after Daniel Cooper, captain of the Unity, a ship active during the peninsula's sealing years. The inlet lay on a traditional Māori shellfish-gathering route from Otakou to what is now St Clair.

The Māori name Puke-tu-roto can mean either "hills standing around a lake" or "hills standing inland". The inlet lay on a traditional Māori route for collecting shellfish that ran from Otakou to what is now St. Clair.

The area is accessible by road from Portobello and Dunedin, with a network of walking trails throughout the surroundings. Visiting at low tide offers the best views of the exposed flats and the most comfortable walking conditions.

The wetlands behind Allans Beach create habitats for numerous bird species and specialized plant communities found nowhere else nearby. This area often goes unnoticed by casual visitors but rewards those who explore it with excellent birdwatching opportunities.
