Crocker Range National Park, known as Taman Negara Banjaran Crocker in Malay, was created in 1984. Before this, the area was protected as a forest reserve. The park covers the north-south Crocker Range, which has mountains that are 1,200 to 1,800 meters high in Sabah, Malaysia. Near the park's headquarters, there is a resort that offers lodging and meals. Other visitor facilities include an exhibition center, insectarium, fernarium, observation tower, and hiking trails.

The park covers 1,399 square kilometers, making it the largest park in Sabah. It includes both hill and mountain forests, home to many plant and animal species found only in Borneo. Keeping this forest healthy is important for providing clean water to towns and communities in Sabah.

The park is home to at least five primate species, including orangutans, gibbons, the furry tarsier with its large round eyes, and the very social long-tailed macaques. The Padas River divides the mountain range between Beaufort and Tenom.

Crocker Range Park is administered by Sabah Parks.
