Grand Župan, also Great or Chief Župan (Serbian: Велики жупан, Veliki župan, Latin: magnus iupanus, Greek: ζουπανος μεγας, romanized: zoupanos megas) is a common English rendering of a medieval South Slavic title that designates a hierarchically senior župan, who is first among, or superior to other župans (chiefs of a regional units called župa). It was most commonly attested in Medieval Serbia, where it was used as a princely title by rulers of the Grand Principality of Serbia, from the end of the 11th century, up to 1219, when it was replaced by royal title, upon the established of the Kingdom of Serbia.
