Black Mountain, Mountain summit in Canberra, Australia.

Black Mountain is a hill of white quartz Black Mountain Sandstone rising to 812 metres AHD, 256 metres above Lake Burley Griffin, west of Canberra's central business district. Near the summit stands Telstra Tower, 195 metres tall. The Australian National Botanic Gardens and the CSIRO occupy the eastern base beside the Australian National University.

The first European settlers named the hill Black Hill, alongside nearby Red Hill, and called the surrounding formation the Canberry Ranges. The name explains why it is not Mount Black, unlike Mount Majura and Mount Ainslie. It later became Black Mountain.

The Ngunnawal name Galambary marks Black Mountain as a sacred meeting and business site, used mainly for men's business and as an initiation site. The mountain itself is said to represent a boy's growth into a man, and with nearby Mount Ainslie it is referred to as women's breasts.

The summit is reached on foot from the Australian National Botanic Gardens at the eastern base, next to the Australian National University, or by road; Telstra Tower stands 195 metres above the top. Tracks cross the slopes, so wear sturdy shoes and carry water. The mountain lies west of the central business district on the northern shore of Lake Burley Griffin.

The mountain's slopes contain different rock types, including State Circle shale and older stones from the Ordovician period. This geological variety makes it of special interest to scientists and reveals deep layers of Australia's earth history.
