洛夫格伦半岛是南极洲的半岛，位于埃尔斯沃思地的瑟斯顿岛东北部，处于卡德瓦拉德湾和摩根湾之间，长40公里，在1960年2月由美国海军发现，现时由南极条约体系管理。

Lofgren Peninsula (72°12′S 96°4′W / 72.200°S 96.067°W / -72.200; -96.067) is an ice-covered peninsula about 22 nautical miles (40 km) long, projecting between Cadwalader Inlet and Morgan Inlet on the northeast side of Thurston Island, Antarctica. It was discovered in helicopter flights from the USS Burton Island and the USS Glacier of the U.S. Navy Bellingshausen Sea Expedition in February 1960, and was named by the Advisory Committee on Antarctic Names for Charles E. Lofgren, personnel officer with the Byrd Antarctic Expedition, 1928–30.
