Tianmen (simplified Chinese: 天门; traditional Chinese: 天門; pinyin: Tiānmén; lit. 'sky gate') is a sub-prefecture-level city (sometimes considered a county-level city) in central Hubei Province, China.

It is on the Jianghan Plain, on the west side of Wuhan (the biggest city of Central China, as well as the capital of Hubei) and the east of Jingzhou (a famous city in Chinese history). Formerly known as Jingling (竟陵), it was renamed to Tianmen in 1726 during the Qing dynasty. The name comes from the Sky Gate Mountains (meaning “tianmen” in Chinese) which lie northwest of the city.

It is the hometown of Lu Yu, the writer of The Classic of Tea, who is respected as "the Sage of Tea" for his contribution to the tea culture. Tianmen has the largest population among the same-level cities in Central China. It was honoured "National Civilized City" by Chinese government in 2014.
