Mount Liebig, Mountain summit in MacDonnell Ranges, Australia

Mount Liebig is a mountain in the southern Northern Territory of Australia, reaching 1,274 metres (4,180 ft) AHD and standing as one of the highest peaks of the MacDonnell Ranges. It lies just north of the Tropic of Capricorn, about 300 kilometres west of Alice Springs, with the nearby settlements of Mount Liebig and Haasts Bluff and the intermittent Lake Mackay to the west.

Explorer Ernest Giles named this mountain in the 19th century after German chemist Justus von Liebig during his travels through the region. The naming reflects how European exploration connected scientific recognition with newly mapped places.

The area around Mount Liebig is home to Aboriginal artists Nora Andy Napaltjarri and Ngoia Pollard Napaltjarri, who have lived in the region. In 1932 two Aboriginal men were killed near the mountain under traditional law; missionary Ernest Kramer demanded prosecution, and a Darwin jury acquitted the accused, a case that raised the question of whether white law applied to traditional violence.

Visitors need four-wheel-drive vehicles to reach this location on unsealed roads in a remote area. It is important to bring plenty of water and supplies since facilities are limited in the surrounding region.
