'''Plankalkül''' ({{IPA|de|ˈplaːnkalkyːl}}) is a [[programming language]] designed for engineering purposes by [[Konrad Zuse]] between 1942 and 1945. It was the first [[high-level programming language]] to be designed for a computer. Zuse never implemented Plankalkül on any of his Z-series machines.<ref>{{Cite web |title=PLANKALKÜL by Bernhard Behr |url=http://cl-informatik.uibk.ac.at/teaching/ss15/bob/slides/BB.pdf}}</ref>

''Kalkül'' (from Latin ''[[Calculus (disambiguation)|calculus]]'') is the [[German language|German]] term for a [[formal system]]—as in ''Hilbert-Kalkül'', the original name for the [[Hilbert-style deduction system]]—so ''Plankalkül'' refers to a formal system for planning.<ref name="Zenil_2012"/>
