Kornicker Glacier (78°43′S 84°35′W / 78.717°S 84.583°W / -78.717; -84.583) is a glacier draining northeastwards from the cirque bounded by Mount Liptak, Mount Southwick, Mount Milton and Mount Mullen in the southern Sentinel Range of the Ellsworth Mountains in Antarctica. The glacier flows along the northwestern side of Petvar Heights and merges with the terminus of the southeast-flowing Thomas Glacier as both glaciers emerge from the range.

Kornicker Glacier was named by the Advisory Committee on Antarctic Names (2006) after Louis S. Kornicker, a research zoologist at the Department of Invertebrate Zoology (Crustacea), National Museum of Natural History, Smithsonian Institution, 1964–2006, and a member of the Board of Associated Editors, Antarctic Research Series, American Geophysical Union, 1978–90.
