Batang Gadis is a national park covering 1,080 km2 in North Sumatra province, Indonesia extending between 300 and 2,145 metres altitude.

The protection of Batang Gadis as a national park is part of a plan to create the Northern Sumatra biodiversity conservation corridor, which would be connected, via a series of protected areas and forests, to Gunung Leuser National Park in the north of the island.

By sampling of a 200 square metres area, researchers found 242 vascular plants or about 1 percent of all flora in Indonesia.

[4] The mammals that can be found are Sumatran tiger, Malayan tapir, Malayan porcupine, Asian golden cat, leopard cat, Indian muntjac, goral (Naemorhedus sumatrae), Java mouse-deer, binturong, sun bear and Sambar deer.

There were 13 endemic species of bird recorded in the park, including Salvadori's pheasant and Schneider's pitta.
