The Antarctic Plate is a tectonic plate containing the continent of Antarctica and extending outward under the surrounding oceans. The Antarctic Plate is bounded almost entirely by extensional mid-ocean ridge systems. The adjoining plates are the Nazca Plate, the South American Plate, the African Plate, the Indo-Australian Plate, the Pacific Plate, and, across a transform boundary, the Scotia Plate.

The Antarctic plate is roughly 60,900,000 square kilometers.[1] It is the fifth biggest plate in the world.

The Antarctic plate movement is estimated at least 1 centimeter/per year towards the Atlantic Ocean.[citation needed]
