Mount Barrington, a mountain that is part of the Mount Royal Range, is located on the Barrington Tops plateau in the Mid-Coast Council within New South Wales, Australia and has an elevation of {{convert|1555|m}} above sea level.

Now the remnants of a volcano, Mount Barrington, formerly the Barrington Volcano, erupted near its present peak between 44 and 54 million years ago. The eruption caused a {{convert|700|km3|adj=on}} basalt flow, which covered much of the Barrington Tops plateau. The lava was up to {{convert|1000|m}} thick.

The extensive rainforests in the area grow on much of the resultant red/brown soils.{{cite book|title=New South Wales Rainforests: The Nomination for the World Heritage List|first=Paul|last=Adam|year=1987|isbn=978-0-7305-2075-7|page=78|publisher=The Service }} Gemstones such as zircon, sapphire, sapphirine and ruby were formed from the volcano.{{cite journal|author1=Sutherland, F.

The surrounding area is covered by sub alpine Snow Gum woodland, with rainforest on the escarpment edge and in fire free gullies.
