The Lanzhou–Chengdu Pipeline is a crude oil pipeline in China. Connected to the Ürümqi–Lanzhou pipeline, it transports crude oil produced in Xinjiang as also imported through the Kazakhstan–China oil pipeline to south-western China.

Capacity of the pipeline is 20,080 barrels per day (3,192 m3/d), equal to 10 million tons per year. The pipeline has a diameter of 24 inches (610 mm). It uses X65 spiral submerged-arc-welded pipes. Its maximum working pressure is 13.4 megapascals (1,940 psi), and its hydraulic head is 2,207 metres (7,241 ft). It has the highest pipe pressure and largest hydraulic head among the pipelines in China.
The cost about US$527 million.
