Kinabalu Park (Malay: Taman Kinabalu), established as one of the first national parks of Malaysia in 1964, is Malaysia's first World Heritage Site designated by UNESCO in December 2000 for its "outstanding universal values" and the role as one of the most important biological sites in the world with more than 4,500 species of flora and fauna, including 326 bird and around 100 mammal species, and over 110 land snail species.

Located on the west coast of Sabah, Malaysian Borneo, it covers an area of 754 square kilometres surrounding Mount Kinabalu, which at 4,095.2 meters, is the highest mountain on the island of Borneo.

The park is one of the most popular tourist spots in Sabah and Malaysia in general. In 2010, the park received 611,624 visitors, including 47,613 climbers.

The site has been identified by UNESCO as a Centre of Plant Diversity for Southeast Asia, as it contains representatives from at least half of all Borneo’s plant species and is extremely rich in species with elements from China, Australia, the Himalayas, Malaysia and pan tropical floras.

British colonial administrator and naturalist Hugh Low led an expedition from Tuaran to the region in 1851. He also became the first recorded man to reach the peak of Mount Kinabalu. The highest peak of the mountain was later named after him—Low's Peak.

The region was designated as a national park in 1964, a decision influenced by expeditions led by botanist E. J. H. Corner for the Royal Society in 1961 and 1964.

Kinabalu Park is situated on the Crocker Range on the western coast of Sabah. It is located within the district of Ranau, within the West Coast Division. The park is not to be confused with Crocker Range National Park which is a separate park in the south.

The park headquarters is 88 kilometres away from the city of Kota Kinabalu. There are sealed roads leading towards the park headquarters from other parts of Sabah. It is situated on the southern boundary of Kinabalu Park, at an elevation of 1,563 m (5,128 ft).
