Gerhard von Malberg (born c. 1200, died after 1245) was the sixth Grand Master of the Teutonic Order, serving from c. 1241 to 1244.
He was forced to resign from the office, and he does not appear in lists of the order's Grand Masters compiled in the 15th and 16th centuries.
He is recorded as holding this office in February 1242, when he represented Frederick II at the Roman curia.
Frederick II dispatched the new Grand Master, the Archbishop of Bari Marino Filangieri, and the Magister Roger Porcastrello to pressure the papal conclave to elect Otto of St. Nicholas as pope, but Pope Celestine IV was chosen instead.
The pope gave Gerhard an apostolic ring, representing Prussia as a papal fief of the knights in return for annual tribute from the Order.
