Tyrrell Glacier (54°22′S 36°31′W / 54.367°S 36.517°W / -54.367; -36.517) 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 (1883–1961). Tyrell was a senior lecturer in geology at the University of Glasgow from 1919–48, and authored several papers on the petrology of South Georgia, the South Shetland Islands, and the Palmer Archipelago area.
