宁尼斯冰川是南极洲的冰川，位于乔治五世海岸，在1912年由澳大利亚探险家率领的探险队发现，该冰川由澳洲南极洲领地管辖。

Ninnis Glacier (68°22′S 147°0′E / 68.367°S 147.000°E / -68.367; 147.000) is a large, heavily hummocked and crevassed glacier descending steeply from the high interior to the sea in a broad valley, on George V Coast in Antarctica. It was discovered by the Australasian Antarctic Expedition (1911–14) under Douglas Mawson, who named it for Lieutenant B. E. S. Ninnis, who lost his life on the far east sledge journey of the expedition on 14 December 1912 through falling into the Black Crevasse in the glacier.
