Vladika or Wladika (Serbian: владика) is a Slavic title and address of bishops in the Eastern Catholic Church and Eastern Orthodox Church. In Old Church Slavonic, the meaning of the word is equivalent to the English: [[Mr.|Mister]].
From the early-16th to the mid-19th century in Montenegro, the title referred to the bishop of Cetinje, who also served as the spiritual leader and the prince of the Prince-Bishopric of Montenegro.
