Langille Glacier is an alpine glacier on the north slope of Mount Hood in Oregon at an average elevation of about 7,500 feet. It lies entirely within the Mount Hood Wilderness and connects to Eliot Glacier to the south. Named for William Alexander Langille, a supervisor of Tongass National Forest, it forms part of Mount Hood’s glaciated upper landscape. As one of the named glaciers associated with Oregon’s highest peak, it is a notable feature of the mountain’s northern flank.
