Hermann von Salza was the fourth Grand Master of the Teutonic Knights, serving from 1210 to 1239. A skilled diplomat with ties to the Frederick II and the Pope, Hermann oversaw the expansion of the military order into Prussia.

The grand master of the Teutonic Order is the supreme head of the Teutonic Order. It is equivalent to the grand master of other military orders and the superior general in non-military Roman Catholic religious orders. Hochmeister, literally "high master", is only used in reference to the Teutonic Order, as Großmeister is used in German to refer to the leaders of other orders of knighthood.
