Gerhard V of Holstein-Plön

Gerhard V of Holstein-Plön (c. 1315–1350) was the only son of Count Gerhard IV and Anastasia of Schwerin. About 1323, aged eight, he inherited Holstein-Plön on his father's death, but he never formally ruled the county and lived as a landowner and a canon and provost of Lübeck Cathedral.

He died on 22 September 1350, unmarried and without children, leaving Holstein-Plön to his uncle John III of Kiel, who thus reunited Plön with Kiel.
