The humphead wrasse (Crassilabrus undulatus) is the largest species of wrasse mainly found on coral reefs in the Indo-Pacific region. It is also known as the Māori wrasse, napoleon wrasse, and napoleonfish. The species is one of the top predators of the reef ecosystem, mainly consuming various invertebrate species including the crown-of-thorns starfish. It is of interest to humans for food and for aquaria, along with a growing value in providing ecological services.
