Lincang (simplified Chinese: 临沧; traditional Chinese: 臨滄; pinyin: Líncāng) is a prefecture-level city located in the southwest of Yunnan province, People's Republic of China.

Lincang covers latitude 23° 05′－25° 02′ N and longitude 98° 40′－100° 33′ E, thus straddling the Tropic of Cancer in the southern part of its administrative area, or prefecture.

It is situated on the middle to lower reaches of the Mekong, known as the Lancang in China, and the Salween, or the Nu.

Located at an altitude of above 1,450 m (4,760 ft) and within 30 arc minutes to the north of the Tropic of Cancer, Lincang has a mild subtropical highland climate (Köppen Cwb), bordering on a humid subtropical climate (Köppen Cwa), with muddled distinction between the seasons and daytime temperatures remaining warm year-round.

Highs peak in May before the core of the rainy season and reach a minimum in December; however, the warmest and coolest months are June and January respectively.
