Adolf Stachel (born 28 February 1913 in Augsburg, died 1971 in Frankfurt am Main) was a German chemist, researcher and inventor, who worked as a researcher at the chemical and pharmaceutical company Cassella (now Sanofi) in Frankfurt-Fechenheim for much of his career.

He held a doctoral degree in chemistry (Doktor-Ingenieur) from the Technische Hochschule München. Early in his career, he was a mentee and collaborator of the Nobel Prize-winning chemist Hans Fischer, who was his doctoral supervisor. He later became a researcher at Cassella. His patents were related to basically substituted heterocyclic compounds, e.g. 2,3-benzotriazine-4(3H)-one derivatives (coumarin), and basically substituted 1H,3H)-quinazoline-2-thion-4-one derivatives, having excellent coronary dilator properties. Patentee was Cassella. When working at Cassella, he was a close collaborator of Armin K.W. Kutzsche. Together with Werner Zerweck they developed Nu-nu-dibenzylsulfamyl benzoic acid, US patent 2805250 A, in the early 1950s. Other frequent collaborators were Rudi Beyerle, Rolf-Eberhard Nitz and Klaus Resag.

He was married to Ingeburg Lydia Katharina Rohde.
