Gabbro Hills () is a group of rugged ridges and coastal hills which borders the Ross Ice Shelf between the Barrett and Gough Glaciers and extends south to Ropebrake Pass. So named by the Southern Party of New Zealand Geological Survey Antarctic Expedition (NZGSAE) (1963–64) because of the prevalence of gabbro, a dark, plutonic rock, in the area.
