Barison Peninsula is the mostly ice-covered peninsula projecting 19km (12miles) in northwest direction from Graham Coast in Graham Land, Antarctica. It is 12km (07miles) wide between Beascochea Bay to the northeast and Leroux Bay to the southwest. The area was possibly visited by the 1897–99 Belgian expedition under Adrien de Gerlache and the 1903–05 French expedition under Jean Charcot.
The peninsula was named by the 1973–74 Chilean Antarctic Expedition for Captain Eduardo Barison Roberts, commander of the expedition naval vessel Yelcho.
Barison Peninsula is centred at -65.6167°N -64.0333°W. The British mapped the peninsula in 1971 and 1976.
