The black-bellied storm petrel (Fregetta tropica) is a species of seabird in the family Oceanitidae.

It is found in Antarctica, Argentina, Australia, Bouvet Island, Brazil, Chile, Falkland Islands, French Polynesia, French Southern Territories, Madagascar, Mozambique, New Zealand, Oman, Peru, Saint Helena, São Tomé and Príncipe, Solomon Islands, South Africa, South Georgia and the South Sandwich Islands, Uruguay, and Vanuatu.

A broad black stripe runs down the center of the belly, but may be broken or absent altogether.

They have long legs, so the feet can be seen beyond the tail in flight.

Noises can be heard from the breeding colonies; birds on the ground give a drawn-out shrill whistle.
