The Petrel Base () is a permanent Argentine scientific station located on Dundee Island, in the Joinville Group, Graham Land which is a part of the Argentinian claim on Antarctica.
The base, which is 18m above sea level, is 37 km from Esperanza Station and over 1300km from port Ushuaia.
Opened as a permanent base on 22 February 1967, it is being used as a temporary base since 1978.
In 2021, the Argentine government announced plans to construct two runways at the base, with a view to reopening it as a permanent base.
