Wulingyuan ([ù.lǐŋ.ɥɛ̌n], Chinese: 武陵源) is a scenic and historical site in the Wulingyuan District of South Central China's Hunan Province. It was inscribed as a UNESCO World Heritage Site in 1992. It is noted for more than 3,000 quartzite sandstone pillars and peaks across most of the site, many over 200 metres (660 ft) in height, along with many ravines and gorges with picturesque streams, pools, lakes, rivers, and waterfalls. It features 40 caves, many with large calcite deposits and a natural bridge named Tianqiashengkong (meaning 'bridge across the sky'), which is one of the highest natural bridges in the world. The site also provides habitat for many vulnerable species, including the dhole, Asiatic black bear, and Chinese water deer.

The site is situated in Zhangjiajie City and lies about 270 kilometres (170 mi) to the northwest of Changsha, the capital of Hunan Province. The park covers an area of 690 square kilometers (266 square miles). Wulingyuan forms part of the Wuling Mountain Range. The scenic area consists of four national parks, which are the Zhangjiajie National Forest Park, Suoxi Valley Nature Reserve, Tianzi Mountain Nature Reserve, and the recently added Yangjiajie Scenic Area. Overall there are over 560 attraction sights to view.

The quartzite sandstone pillars and the surrounding regions were formed during the Devonian period (400 to 350 million years ago) from a combination of tectonic uplift and water erosion. The highest area in the park is Huang Shi Zhai (黃石寨). It reaches a height of 3,450 feet (1,050 m) and is accessible via cable car or a set of stairs. Another cliff is accessed by the 326 m (1,070 ft) Bailong Elevator.
