The Auckland teal (Anas aucklandica) (), also known as Auckland Islands teal, is a species of dabbling duck of the genus Anas that is endemic to Auckland Islands south of New Zealand. The species was once found throughout the Auckland Islands, but is now restricted to the islands that lack introduced predators: Adams Island, Enderby Island, Disappointment Island and a few smaller islands. An old report of "the same flightless duck" on North East Island, The Snares group most likely refers to a straggler.
The Auckland teal is smaller and rarer than the brown teal of the main islands of New Zealand, a species with which it was once considered conspecific. The plumage is all over brown with a hint of green on the neck and a conspicuous white eyering. The female is slightly darker than the male. The wings are very small and the species has, like the related Campbell teal, lost the power of flight.
