Shangchen (Chinese: 上陈) is a Lower Palaeolithic archaeological site in Lantian County, Shaanxi, China, some 25 km south of Weinan. It was discovered in 1964, and excavated during 2004 and 2017.

Stone tools found at the site were dated based on magnetostratigraphy in a 2018 study. Artefacts were found in 17 layers, dated to between 1.26 Ma (palaeosol S15) and 2.12 Ma (loess L28). The date of 2.12 Ma predates the earliest known fossils of archaic humans in Eurasia (Homo erectus georgicus) by 300,000 years.
