Cat Tien National Park is an important national park found in the south of Vietnam, approximately 150 km north of Ho Chi Minh City. It protects one of the largest areas of lowland tropical rainforests left in Vietnam.

Cat Tien National Park consists of evergreen tropical and deciduous forest, dominated by Dipterocarpaceae, Fabaceae and Lythraceae (especially Lagerstroemia spp.), with 40% of the park comprising bamboo woodland, and the remaining 10% farmland, wetlands and grassland. The park fauna is impressive, if highly threatened, comprising of such impressive megafauna as Javan Rhinos (one of only two populations in the world), Asian Elephants, Gaur, Sun Bears and, possibly, Banteng, and wild Water Buffalo. Some accounts also list tigers, Leopards, Clouded Leopards, Dholes and Asiatic black bears, however a recent series of surveys did not confirm this. The park also holds hosts of smaller mammal species, including Yellow-cheeked Gibbons, Silvery Langurs, Crab-eating Macaques, Pygmy Slow Loris, as well as civets, mouse deer, and treeshrews.

The park also has impressive bird species including White-winged Ducks, Siamese Firebacks, Great Hornbills and Black Eagles.
