Charles Wilson Greene (1866–1947) was an American professor of physiology and pharmacology from Indiana.
He was a physiology instructor from 1893 to 1896, when he began his Ph.D. at Johns Hopkins with Henry Newell Martin.
There, he established the first laboratory for experimental pharmacology in the Mississippi Valley.
His researches covered the structure and function of phosphorescent organs in the toadfish, the circulatory system of the hagfish, the physiology of the Chinook salmon, and the influence of inorganic salts on the cardiac tissues.
The Shoshone sculpin (Cottus greenei) was named in honour of Greene by Charles Henry Gilbert and George Bliss Culver in 1898.
