Ferrar Glacier is a glacier in Antarctica. It is about long, flowing from the plateau of Victoria Land west of the Royal Society Range to New Harbour in McMurdo Sound. The glacier makes a right (east) turn northeast of Knobhead, where it is apposed, i.e., joined in Siamese-twin fashion, to Taylor Glacier. From there, it continues east along the south side of the Kukri Hills to New Harbour.
