Caspar Stoll (Hesse-Kassel, probably between 1725 and 1730 - Amsterdam, December 1791) was either a clerk or a porter at the Admiralty of Amsterdam. He is best known for the publication of most of the descriptions and plates of De Uitlandsche Kapellen, a work on butterflies, started by Pieter Cramer. He also published several works of his own on other insect groups. Stoll's publication on stick insects, mantids and their relatives is particularly well known.
