Murlen National Park, National park in Champhai district, Mizoram, India.

Murlen National Park is a nature reserve located in the hills of Champhai district near the Myanmar border. The landscape features subtropical forests with dense tree coverage and multiple hiking trails across hilly terrain.

Murlen National Park was declared in 1991. It lies at Murlen Village, part of Hnahlan Village, in the territory of Saithuama Sailo, chief of Hnahlan. The park covers about 200 km2 in Champhai district, roughly 245 km east of Aizawl and close to the Chin Hills, north of Lengteng Wildlife Sanctuary.

Murlen National Park takes its name from Murlen village, part of Hnahlan village, the home village of Saithuama Sailo, chief of Hnahlan. The two Ceropegia species discovered in the park were named for the state and the locality: Ceropegia mizoramensis and Ceropegia murlensis. A forest tract so dark that no sun ray reaches it is known locally as the 'losing area of seven fellow-men', or land of no return.

Murlen National Park lies about 245 km east of Aizawl in Champhai district, close to the Chin Hills and the Myanmar border, and north of Lengteng Wildlife Sanctuary. Access is by road from Aizawl. The park covers roughly 200 km2, and the forest canopy is so dense that on a sunny day only about 1% of sunlight reaches the ground, so carry a torch on trails.

Two pitcher-plant relatives were first described from this forest: Ceropegia mizoramensis and Ceropegia murlensis, named after the state and the park itself. The park also holds an area so shaded that no sunbeam reaches the ground, known as the "losing area of seven fellow-men" or land of no return.
