Landmeister of Prussia was a high office in the Teutonic Order. The Landmeister administered the land of Prussia of the Teutonic Order. It was in existence as a separate office from 1230 to 1309, later being held in union with the office of Grand Master until 1525.^[1]

The office was created at the same time as the beginning of the conquest and the forcible Christianization of the Prussians in the summer of 1230. The first Landmeister, Hermann von Balk, received the Kulmer Land from the Duke Konrad I of Masovia as the nucleus of the Teutonic Orders in Prussia and started advancing north along the Vistula river.^[2] His successors completed the conquest of the country under considerable setbacks and established the protection of the districts and the defeat of rebellious Prussians in fortified houses, the forerunners of the later brick fortresses known as Ordensburgs. The last Landmeister of Prussia residing in Elbing was Heinrich von Plötzke. In 1309, after the death of Plötzke, the office became held in union with that of the Grand Master (held by Siegfried von Feuchtwangen residing in Marburg Castle at the time) and continued as such until 1525.^[3]
