Lyons Cone () is a cone shaped peak north-northeast of the Matterhorn, rising to on the ridge separating the heads of Lacroix Glacier, Newall Glacier, and Suess Glacier in the Asgard Range, Victoria Land, Antarctica. It was named by the Advisory Committee on Antarctic Names after American geochemist William Berry Lyons, a veteran of expeditions to the Himalayas, Greenland, Iceland, and Antarctica, 1980–97, and chief scientist of the McMurdo Dry Valleys Long-Term Ecological Research field team, 1993–97. As a member of a University of New Hampshire field party, 1988–89, Lyons participated in glaciochemical investigations that collected two ice cores, deep, from the upper Newall Glacier, in proximity of this peak.
