Daniel Chee Tsui (崔琦 pinyin: Cuī Qí, born February 28, 1939, Henan Province, China) is a Chinese American physicist whose areas of research included electrical properties of thin films and microstructures of semiconductors and solid-state physics. In 1998, along with Horst L. Störmer of Columbia University and Robert Laughlin of Stanford, Daniel Tsui was awarded the Nobel Prize in Physics for the "discovery of a new form of quantum fluid with fractionally charged excitations" by the Royal Swedish Academy of Sciences.

Daniel Tsui attended Pui Ching Middle School, Kowloon, Hong Kong. He moved to the United States in 1958 to attend Augustana College in Rock Island, Illinois, and graduated Phi Beta Kappa. He received his doctorate in physics from the University of Chicago and was appointed a professor of Electrical Engineering at Princeton in 1982.
