Shangri-La County (Tibetan: སེམས་ཀྱི་ཉི་ཟླ་རྫོང་, Chinese: 香格里拉县; pinyin: Xiānggélǐlā xiàn) is a primarily Tibetan county in northwestern Yunnan province, People's Republic of China and is the location of the seat of the Dêqên Tibetan Autonomous Prefecture.
In the second half of the 20th century the county was called Zhongdian County (Chinese: 中甸县 Zhōngdiàn Xiàn) but was renamed in 2001 after the fictional land of Shangri-La in the 1933 James Hilton novel Lost Horizon, in an effort to promote tourism in the area. The original Tibetan population refers to this place by its traditional name Gyalthang (Standard Tibetan: རྒྱལ་ཐང་རྫོང་), meaning "Royal plains".
Pudacuo National Park, the first national park in China to meet IUCN standards, also incorporates the Three Parallel Rivers of Yunnan Protected Areas World Heritage Site.The town's airport is Diqing Airport. Covering an area of 225 hectares, it is one of the biggest airports in the northwest of Yunnan.
