Tianmen Mountain (Chinese: 天門山; pinyin: Tiānmén Shān) is a mountain located within Tianmen Mountain National Park, Zhangjiajie, in the northwestern part of Hunan Province, China.

A cablecar was constructed by the French company Poma from nearby Zhangjiajie railway station to the top of the mountain. Tianmen Mountain Cableway is claimed in tourist publications as the "longest passenger cableway of high mountains in the world", with 98 cars and a total length of 7,455 metres (24,459 ft) and ascent of 1,279 metres (4,196 ft) The highest gradient is 37 degrees. Tourists can walk on kilometres of paths built onto the cliff face at the top of the mountain, including sections with glass floors. An 11 kilometres (6.8 mi) road with 99 bends also reaches the top of the mountain and takes visitors to Tianmen cave, a natural hole in the mountain of a height of 131.5 metres (431 ft).

A large temple is also located on the summit with chairlift or footpath access. The original temple here was built in the Tang Dynasty. Today a more recent construction with Tang dynasty architecture occupies the site and includes a vegetarian restaurant in the 10000 sq mi of setting.

On September 25, 2011 Jeb Corliss glided through the 100 feet (30 m) wide archway in the mountain using a wingsuit. The flight began from a helicopter at 6,000 feet (1,800 m), and ended with a safe landing on a nearby bridge. The World Wingsuit League held the first and second World Wingsuit Championships in Tianmen.

In August 2016, a glass skywalk overlooking Tongtian Avenue, called the Coiling Dragon Cliff opened to the public.
