Carolyn Wilson Harris (December 8, 1849 – May 3, 1910) was vice president of the Sullivant Moss Society during 1904–1905 and charge of the Lichen Department from 1901 to 1905.

Harris contributed new plants to the Society from around Chilson Lake and helped to determine the classification of other members' submissions.

Harris was the first to publish about lichens in The Bryologist, a scientific journal devoted primarily to mosses, which was edited by Abel Joel Grout and Annie Morrill Smith.

Harris published a series of 12 papers on lichens (see Publications), which provided beginners with an overview of their physiology and directions on how to identify and distinguish them from mosses.

With careful textual descriptions, illustrations, and photographs, Harris hoped to describe lichens well enough that they could be recognized with a simple hand lens.
