南极洲板块，简称南极板块，是一块包括南极洲和周围洋面的板块，面积约16,900,000平方公里。每年正以1公分的速度向大西洋移动。

板块与纳斯卡板块、非洲板块、南美洲板块、斯科舍板块和印度-澳洲板块交界，并正与太平洋板块合并。

The Antarctic Plate is a tectonic plate containing the continent of Antarctica and extending outward under the surrounding oceans. After breakup from Gondwana (the southern part of the supercontinent Pangea), the Antarctic plate began moving the continent of Antarctica south to its present isolated location causing the continent to develop a much colder climate. 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.
