Tung-Yen Lin (November 14, 1912 – November 15, 2003) was a Chinese-American civil engineer. He was born in Fuzhou, Fujian, China. In 1931, he earned a bachelor's degree in civil engineering from Tangshan Jiaotong University. In 1933, he received a master's degree in civil engineering from the University of California, Berkeley. Lin was a Lifetime Honorary Professor at the University of California, Berkeley, Chairman of T.Y. Lin China, and Honorary Chairman of T.Y. Lin International. He was also a member of the U.S. National Academy of Engineering, a foreign academician of the Chinese Academy of Sciences, and an academician of Academia Sinica in Taiwan, China.

Lin received numerous prestigious awards, including the U.S. National Medal of Science, the first Pre-stressed Concrete Award from the American Society of Civil Engineers (later renamed the Tung-Yen Lin Award). Professor Lin was one of the pioneers of prestressed concrete theory and design and a world-renowned master in civil engineering structures. He made innovative contributions to the design of long-span bridges and seismic structures for high-rise buildings. He established several theories on prestressed concrete, which he validated through experiments and practical applications. His numerous works on prestressed structures, steel structures, bridges, and building systems were translated into various languages across Europe and Asia, gaining global recognition. Lin's personal achievements, publications, and innovative engineering projects won nearly one hundred awards.
