Tyrrell Glacier () is a glacier flowing north into the head of Moraine Fjord where it joins Harker Glacier, on the north coast of South Georgia.
In 1982, the United Kingdom Antarctic Place-Names Committee (UK-APC), in association with Harker Glacier, named the Tyrell Glacier after George Walter Tyrrell (1883âÂÂ1961). Tyrell was a senior lecturer in geology at the University of Glasgow from 1919âÂÂ48, and authored several papers on the petrology of South Georgia, the South Shetland Islands, and the Palmer Archipelago area.
