Thomas Corwin Mendenhall (born Oct. 4, 1841, Hanoverton, Ohio, U.S.—died March 23, 1924, Ravenna, Ohio) was an American physicist and meteorologist, the first to propose the use of a ring pendulum for measuring absolute gravity.

Mendenhall was a professor at Ohio State University, Columbus, in 1873–78 and from 1881 until he was named professor emeritus in 1884, when he became a professor for the U.S. Signal Corps. In 1878–81 he was a visiting professor at the Tokyo Imperial University, where he helped develop the Japanese government’s meteorological system, and in 1889 he was appointed superintendent of the U.S. Coast and Geodetic Survey; he served as president of the Worcester (Mass.) Polytechnic Institute from 1894 until 1901, when he moved to Europe for 11 years of work.
