Cape Brett is a promontory on the northern North Island coast in New Zealand. Located at the end of the Cape Brett Peninsula, the head extends north into the Pacific Ocean at the eastern end of the Bay of Islands.
A lighthouse stands at the end of the peninsula, which rises to 360 metres at its northern end. A noted landmark, the natural arch ('Hole in the Rock') of Piercy Island, lies two kilometres off the cape.
