Hans Conon von der Gabelentz (13 October 1807 – 3 September 1874) was a German politician who served as prime minister of the Duchy of Saxe-Altenburg from 1848 to 1849.

He devised a standard romanized transliteration system for Manchu whose creation is often incorrectly credited to his compatriot Paul Georg von Möllendorff.

Furthermore, the Abhandlungen (Transactions) of the Gesellschaft der Wissenschaften (Society of Sciences) in Leipzig (1860) contained: Die melanesischen Sprachen nach ihrem grammatischen Bau etc.

Finally, he published the Manchu translation of the Chinese work: Sse-schu, Schu-king, Schi-king, with a Manchu-German lexicon (Leipzig 1864).

The Mitteilungen (Communications) of the Geschichts- und Altertumsforschenden Gesellschaft des Osterlandes (Society for Historical and Archeological Research of the Eastern Lands) contained many valuable articles by him on knowledge of the history of his closer homeland.
