Kumimanu is an extinct species of giant penguin.

It measured about 170 cm long from the tip of its bill to the tip of its flippers, stood around 140 cm tall, and weighed approximately 100 kg. It is the largest known example of penguin. It lived around 60 to 56 million years ago. The species arose after the extinction of the giant dinosaurs.

Fossils were found in New Zealand, and the discovery was announced in December 2017.
