Endau-Rompin National Park, National park in Johor and Pahang, Malaysia.

Endau-Rompin is a national park stretching across Johor and Pahang through mountains, rivers, and waterfalls set in tropical rainforest. The area covers dense forest landscape with varied terrain and numerous streams flowing through its valleys.

The first scientific exploration of the forest took place in 1892, followed by its designation as a protected area in 1933. This early interest reflected growing recognition of the region's ecological importance.

The park's name comes from the Endau and Rompin rivers that flow through it. Near Kampung Peta, a settlement of the Orang Hulu, visitors walk with Jakun guides who recount forest myths and demonstrate tracking and hunting skills. The 120 m Buaya Sangkut waterfall takes its name from a legend of an old crocodile trapped on the rocks.

The park has two official entry points: Kampung Peta on the eastern boundary in Mersing District and Selai on the southwestern boundary in Segamat District. From Kampung Peta, a 40-minute boat ride reaches the Kuala Jasin camping area, from which the walk to Buaya Sangkut waterfall takes about six hours. The park is closed to the public during the monsoon season from November to March, and fishing is banned from September to October.

The Gollum's toad, Ingerophrynus gollum, is known only from this park; it was named after the Lord of the Rings character. The park also once held the largest remaining population of the northern Sumatran rhinoceros on the Malay Peninsula, a species now extinct in the wild across Malaysia.
