List of Oceanian species extinct in the Holocene

This is a list of Oceanian species extinct in the Holocene that covers extinctions from the Holocene epoch, a geologic epoch that began about 11,650 years before present (about 9700 BCE) and continues to the present day.

Oceania is a geographical region in the Pacific Ocean comprising Australasia, Melanesia, Micronesia, and Polynesia. Numerous species across Oceania became extinct as humans moved across the Pacific. Australia-New Guinea, New Zealand, and Hawaii have particularly large numbers of extinct species, so they listed in separate articles. Extinctions from the remaining Pacific Islands are listed below. This list includes sovereign states (such as Fiji) as well as island territories (such as French Polynesia). Extinctions from the associated states and dependent territory of New Zealand are listed below, and not with New Zealand proper. Papua New Guinea's Autonomous Region of Bougainville (part of the Solomon Islands archipelago) is included below, although the rest of Papua New Guinea is covered in List of Australia-New Guinea species extinct in the Holocene.

Many extinction dates are unknown due to a lack of relevant information.
