Mount Gibraltar (Aboriginal: Bowrell) is a mountain with an elevation of 863 metres (2,831 ft) AHD that is located in the Southern Highlands region, between Bowral and Mittagong, in New South Wales, Australia.

[1] The mountain is locally known as 'The Gib', and is in the form of a ridge, rather than an obvious conical peak.

'The Gib' is primarily a residential area with a large nature reserve at its peak.

The former Mount Gibraltar Trachyte Quarries Complex was added to the New South Wales State Heritage Register on 2 December 2013.

[5] The Main South Railway skirts Mount Gibraltar at its western foothills, passing through a tunnel under Evans Street, Bowral.
