The Lanzhou–Chengdu–Chongqing Pipeline is a petroleum product pipeline in China. The pipeline is owned by PetroChina.

The 1250 km pipeline starts at the Lanzhou terminal and finish at the Chongqing terminal. It runs through Gansu, Shaanxi and Sichuan provinces. Its diameter varies from 508 mm to 457 mm to 323.9 mm. The pipeline has capacity over 6 million tonnes of oil products per year. The pipeline cost around US$500 million.

After the 2008 Sichuan earthquake the pipeline was temporarily closed due to risk of flooding as the pipeline is located 60 km downstream from Tangjiashan Lake.
