Edgar Theodore Wherry (1885–1982) was an American mineralogist, soil scientist and botanist.

He lived in Washington, D.C. from 1912 to 1930, part of this time working as an assistant curator of mineralogy for the U. S. National Museum of Natural History, and also for the Bureau of Chemistry of the United States Department of Agriculture.

The Academy of Natural Sciences of Drexel University preserves many botanical specimens that he collected in Pennsylvania in the 1940s and 1950s.

A crowd-sourcing initiative, organized by the Mid-Atlantic Herbaria Consortium, was digitizing these records in 2020.
