Emerik Derenčin (Hungarian: Imre Derencsényi, Croatian: Mirko Derenčin) was a Hungarian-Croatian nobleman remembered as the commander of the Croatian troops in the 1493 Battle of Krbava Field.

He was a member of the Derencsényi family from the kindred of Balog.^[1] Prior to becoming the ban, Derenčin was the military captain of Senj,^[2] and the ban of Jajce.^[3]

Derencsényi and John Both were named the Ban of Croatia and Dalmatia and Ban of Slavonia in 1493.^[4] In the Battle of Krbava Field, the Croats under Derenčin suffered a devastating loss, and Derenčin himself was taken captive and killed.

Derencsényi married Orsolya Zápolya, sister of Stephen Zápolya, the Palatine of Hungary. They had two sons and, probably, a daughter.^[4]
