Mount Trusmadi or Trus Madi (Malay: Gunung Trusmadi) is a mountain located at the Interior Division of Sabah, Malaysia. It is considered as the second highest mountain in both Sabah and Malaysia at 2,642 metres (8,668 ft), after Mount Kinabalu with the mountain offer a tougher climbing challenge than the latter.
The mountain area is located within the Trusmadi Forest Reserve where it supports a wide range of unique flora and fauna, including Nepenthes macrophylla, a species of pitcher plant. The natural hybrid Nepenthes × trusmadiensis is named after the mountain. In 1999, a small-scale expedition on the mountain biodiversity was conducted through a collaboration between Sabah Museum and Louisiana State University Museum of Natural Science with various bird species are found within the area.
It is one of Sabah's ecotourism and mountain climbing destination. There are three climbing trails towards the mountain summit, namely from Wayaan Kaingaran (Tambunan), Wayaan Mastan (Keningau) and Wayaan Mannan (Sinua, Sook, Keningau). Both Wayaan Kaingaran and Mastan is accessible only with 4WD while Wayaan Mannan has a good access road.
