阿尔茨托夫斯基半岛是南极洲的半岛，位于葛拉汉地西岸，长24公里，处于安沃尔湾和威尔米纳湾之间，由保加利亚的极地探险队发现。

The Arctowski Peninsula (64°45′S 62°25′W / 64.750°S 62.417°W / -64.750; -62.417) is a peninsula, 15 miles (24 km) long in a north-south direction, lying between Andvord Bay and Wilhelmina Bay on the west coast of Graham Land. It was discovered by the Belgian Antarctic Expedition, 1897–99, under Adrien de Gerlache. The name, for Henryk Arctowski of that expedition, was suggested by the Advisory Committee on Antarctic Names for this previously unnamed feature.
