Endau-Rompin National Park (Malay: Taman Negara Endau-Rompin) is a protected tropical rainforest situated within a massif in the southern foothills of the Tenasserim Hills, straddling Segamat and Mersing Districts in northeastern Johor and Rompin District in southern Pahang.

It covers a total land area of approximately 870 km2 (340 sq mi), making it the second-largest national park in Peninsular Malaysia after Taman Negara.

However, dispute between federal and state powers prevented the creation of a national park in the area at that time.

Endau-Rompin is one of the oldest tropical rainforest complexes in the world and features rock formations some 248 million years old.

It used to have the largest remaining population of the threatened Northern Sumatran rhinoceros species on the Malay Peninsula, but they are now extinct in the wild for the whole of Malaysia.
