Perry Daniel Strausbaugh (March 21, 1886 - May 3, 1965) was an American botanist and expert in the flora of West Virginia.

In 1916, Strausbaugh enrolled at the University of Chicago as a graduate student in botany under the direction of John Merle Coulter.

Here, one of his first acts was to re-organize the University Herbarium first established by Charles Frederick Millspaugh and to start to bolster the collection.

He was in charge of growing grass next to landing strips in order to prevent dust clouds from damaging aircraft and other machinery.
