The Vanuatu petrel or Falla's petrel, Pterodroma occulta is a species of gadfly petrel. This little-known seabird was first scientifically described in 2001 based on six specimens taken in 1927 off Merelava, Vanuatu, and a single bird found ashore in 1983 in New South Wales, Australia. The first confirmed breeding locality was only discovered in 2009 on the island of Vanua Lava, Vanuatu, but based on reports by locals it is supposed to also breed on Merelava. The IUCN has not recognized the Vanuatu petrel as a species, but maintain that it as a subspecies of the very similar white-necked petrel, P. cervicalis, with the "combined" species considered vulnerable.
The alternate name commemorates Robert Falla, a New Zealand ornithologist.
This species resembles the white-necked petrel, but is slightly smaller at 40 centimetres (16 in) in length and 300–350 grams (11–12 oz) in weight. It has a black cap, white rear neck, dark grey back, wings and tail, and a darker rump. The underparts are white with dark bases to the primary feathers. Like the white-necked petrel, the upperparts of worn birds become darker.

Vanuatu (English i/ˌvɑːnuːˈɑːtuː/ vah-noo-AH-too or /vænˈwɑːtuː/ van-WAH-too; Bislama IPA: [vanuaˈtu]), officially the Republic of Vanuatu (French: République de Vanuatu, Bislama: Ripablik blong Vanuatu), is a Pacific island nation located in the South Pacific Ocean. The archipelago, which is of volcanic origin, is some 1,750 kilometres (1,090 mi) east of northern Australia, 500 kilometres (310 mi) northeast of New Caledonia, east of New Guinea, southeast of the Solomon Islands, and west of Fiji.
Vanuatu was first inhabited by Melanesian people. The first Europeans to visit the islands were a Spanish expedition led by Portuguese navigator Fernandes de Queirós, who arrived on the largest island in 1606. He then claimed the archipelago for Spain, as part of the colonial Spanish East Indies, and named it Austrialia del Espiritu Santo.
In the 1880s, France and Great Britain claimed parts of the archipelago, and in 1906 they agreed on a framework for jointly managing the archipelago as the New Hebrides through a British–French Condominium. An independence movement arose in the 1970s, and the Republic of Vanuatu was founded in 1980.
