Hippolyt Tschapeck (4 October 1825, Vienna – 11 December 1897, Vienna) was an Austrian malacologist, known for his studies of mollusks native to Styria.
He studied in Nikolsburg and Brünn and at the University of Vienna, where he received his doctorate in 1848. He later became part of the military justice system, rising to the rank of hauptmann-auditor. In retirement he moved to Graz, then in 1887 returned to Vienna.
Earlier in his career he conducted investigations of Coleoptera (beetles), then around 1875 his primary focus turned to the field of malacology. Although he published nothing on Coleoptera, he provided some details for Karel Brančik's "Die Käfer der Steiermark" (1871). He was the author of numerous papers on mollusk fauna in the publication "Nachrichtenblatt der Deutschen Malakozoologischen Gesellschaft".
