Procellaria is a genus of Southern Ocean long-winged seabirds related to prions, and within the order Procellariiformes.

The black petrel (Procellaria parkinsoni) ranges in the Pacific Ocean, and as far north as Central America.

The genus Procellaria was introduced in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his Systema Naturae.

Fossil material of an extinct species Procellaria altirostris discovered in New Zealand and dating from the Pliocene was described in 2021.

Also, they can digest the wax esters for a high energy source of food, during long flights or the period of time that they are incubating their egg or caring for their young.
