A serac (/ sɛˈrækˌˈsɛræk /) (from Swiss French sérac) is a block or column of glacial ice, often formed by intersecting crevasses on a glacier. Commonly house-sized or larger, they are dangerous to mountaineers, since they may topple with little warning. Even when stabilized by persistent cold weather, they can be an impediment to glacier travel.

A serac is a large freestanding column of glacial ice formed when a glacier is broken up by intersecting crevasses, in icefalls or on the faces of the terminal ends of a glacier, especially that of hanging glaciers. Seracs are exceptionally unstable and can fall at any time without warning, making them a serious danger to climbers.
