Johann Zelebor (5 February 1815, in Eggenburg, Lower Austria – 19 February 1869, in Vienna) was an Austrian naturalist, illustrator, and zoologist.
Prior to 1845 he worked as a carpenter, afterwards serving as a taxidermist at the Naturalien-Cabinet in Vienna. In 1857 he became an assistant at the aforementioned institution, later receiving a promotion as a "curator-adjunct".
He took part in the expedition Reise der österreichischen Fregatte Novara um die Erde (1861–1876) ("Journey of the Austrian frigate Novara around the Earth, 1861 - 1876"). In addition to the Novara expedition, Zelebor took zoological journeys to the Balkans, Crete and Egypt during his career.[1]
