Principality of Gützkow was an independent principality in Western Pomerania that existed in the Middle Ages until c. 1128. It was inhabited by the Lutici tribe and was centred around its capital, Gützkow. Around 1128, it was conquered by the Duchy of Pomerania and reorganised into Castellany of Gützkow. The sources written by Otto mention princeps Mitzlaw of Gützkow to be the ruler of the state around 1128.
Until the 12th century, the burgh of Gützkow was a center of the principality inhabited by the Lutici tribe. By the time when Otto of Bamberg had converted the area into Christianity, the state was already conquered by the Duchy of Pomerania and reorganized into Castellany of Gützkow.
