Wai Yiu Cheung (July 15, 1933 – before 1998) was a Chinese-American biochemist at St. Jude Children's Research Hospital in Memphis, Tennessee, known for his discovery of calmodulin and his work on the function of calcium. He coined the term "calmodulin" in 1978 for an activator protein of phosphodiesterase that he discovered, which regulates a wide range of calcium-dependent processes and the calcium level itself. Cheung was a member of the Academia Sinica and received the Gairdner Foundation International Award in 1981. He was also a professor at the University of Tennessee.
