Charles Schweinfurth (April 13, 1890 – November 16, 1970) was an American botanist and plant collector who distinguished himself by his studies on orchids. He predominantly collected species from Peru which he described in his four volume reference work Orchids of Peru (1958). He was a researcher at the Botanical Museum of Harvard University, and director of the Ames Orchid Herbarium where, in 1958, he was succeeded by Leslie Andrew Garay.
