Mount Aspiring / Tititea is New Zealand's 23rd-highest mountain. The peak's altitude of 3,033 metres (9,951 ft) makes it the country's highest outside the Aoraki / Mount Cook National Park region.

Māori named it Tititea, after a chief of the Waitaha iwi, who were the first people to settle the South Island.

It was named Aspiring in December 1857 by the Chief Surveyor for the Otago Province, John Turnbull Thomson.

It is also often called "the Matterhorn of the South", for its pyramidal peak when seen from the Matukituki River.

The mountain's name was used for the surrounding Mount Aspiring National Park at its creation in 1964.

The mountain's official name was updated to Mount Aspiring / Tititea in 1998, by the Treaty Settlement Legislation Section 269 and Schedule 96 of the Ngāi Tahu Claims Settlement Act 1998.

Mount Aspiring / Tititea sits slightly to the west of the main divide, 30 kilometres west of Lake Wānaka. It lies at the junction of three major glacial systems – the Bonar Glacier, which drains into the Waipara River, and the Volta and Therma glaciers, which both drain into the Waiatoto River. The Waipara is a tributary of the Arawhata River, and both the Arawhata and Waitoto Rivers flow out to the West Coast in between Haast and Jackson Bay.

The first ascent was on 23 November 1909 by Major Bernard Head and guides Jack Clarke and Alec Graham. Head's party climbed to the summit ridge by the west face from the Bonar Glacier, a route not repeated until 1965.
