Gill Pinnacle (or Gill's Pinnacle) is an inselberg in the far east of Western Australia, on the Ngaanyatjarra Lands. It is part of the Petermann Ranges. It consists of a dome-shaped hill, surrounded by dense shrub; its top is bare rock. The hill has been useful as a landmark, because it marks the location of one of the area's most reliable freshwater rockholes, Gordon's Springs. This is a few hundred meters to the north of the rock. The area is called (also spelled ' or ') in Pitjantjatjara and Ngaanyatjarra.
