Lugg Island is a small island in the Donskiye Islands group lying 2 km (1.2 mi) north-west of Lake Island, off the west end of Breidnes Peninsula, Vestfold Hills, Antarctica. It was first plotted from aerial photos taken by the Lars Christensen Expedition, 1936–37, and was named by the Antarctic Names Committee of Australia for Dr. D. Lugg, medical officer at Davis Station in 1963, who visited the island for biological studies.
