Tung-Mow Yan (Chinese: 顏東茂; born 1937) is a Taiwanese-born American physicist, who has specialized in theoretical particle physics; primarily in the structure of elementary particles, the standard model, and quantum chromodynamics. He is professor emeritus at Cornell University.
He graduated with a BS in physics in 1960 at National Taiwan University (NTU), an MS in physics at National Tsing Hua University (Hsinchu) in 1962, and earned a Ph.D. in physics in 1968 at Harvard University, under the supervision of Julian Schwinger.
From 1970 to 2009 Yan worked at Cornell University, in particular the Cornell High-Energy Synchrotron Source and Laboratory for Elementary-Particle Physics (combined into the Cornell Laboratory for Accelerator-based Sciences and Education as of 2006). He became a professor in 19??. By 2010 he reached the status of professor emeritus in physics.

In the 1970s, Yan and Sidney Drell investigated the important Drell–Yan process of massive lepton pair production in hadronic collisions, which provides a crucial experimental probe into the parton distribution functions. These describe the way that the momentum of an incoming high-energy nucleon is partitioned among its constituent partons.
