Heinrich Carl Küster was a German malacologist and entomologist.
From 1836, he worked as an instructor at a trade school (Gewerbschule) in Erlangen. He conducted scientific excursions in Sardinia (1831) as well as in Dalmatia and Montenegro (1840–41).
He was the originator of "Die Käfer Europas, nach der Natur beschrieben" (Beetles of Europe, described from nature), a multi-volume series (1844-1912) that was continued by Ernst Gustav Kraatz and Friedrich Julius Schilsky. Also, he provided drawings for Carl Wilhelm Hahn's ornithological work, "Voegel, aus Asien, Africa, America, und Neuholland, in Abbildungen nach der Natur mit Beschreibungen".
