The Campbell Teal or Campbell Island Teal (Anas nesiotis) is a small, flightless, nocturnal species of dabbling duck of the genus Anas endemic to the Campbell Island group of New Zealand. It is sometimes considered conspecific with the Brown Teal. The plumage is similar to that of the Auckland Teal, dark sepia with the head and back tinged with green iridescence, and a chestnut breast on the male, with the female dark brown all over.
