Jordan Lupin (Italian: Giordano Lupino; died 1197) was the first count of Bovino in the Norman kingdom of Sicily. He played a major role in the final years of Norman rule and first years of the Staufer dynasty. Twice he was involved in opposing crusader armies passing through Sicily. In the second instance, he led a revolt, apparently in the hope of seizing the throne. He was successful in attracting significant support, but was ultimately captured and executed.
Jordan was a son of Count Hugh I and Countess Clementia of the county of Catanzaro. He had an elder twin brother, Count Hugh of Conversano, who later inherited Catanzaro. Jordan's surname, Lupin (Latin: Iordanus Lupinus), was shared by his father and brother. It was mangled, however, by the English chronicler Roger of Hoveden into "Jordanus de Pino" or "Jordanus del Pin", whence the French historian Ferdinand Chalandon modernised it into "Jourdain du Pin". Two manuscripts of the Itinerarium Regis Ricardi of Richard de Templo, however, correctly render it Luppin, and the Norman poet Ambroise calls him "Jordanz Lupins" in the Norman dialect.
In Palermo in May 1183, Jordan witnessed the royal diploma permitting the marriage of Roger of Tarsia and Maria, daughter of Robert Malconvenant. By the later 1180s, he was a member of the royal bodyguard and later the royal seneschal (regis senescalcus) under William II in March 1187. He was also the lord of Tavis, that is, the region around Mount Altesina in the Heraean Mountains of central Sicily. In the succession dispute that followed William's death in 1189, he supported Tancred, who rewarded him with the county of Bovino. This county was a new creation, having been carved out of the south of the county of Loritello. It also included Deliceto, Montellere and Monterisi. The historian Errico Cuozzo suggests that Jordan was only granted the county of Bovino as compensation for the loss of Messina.
