Chronicon terræ Prussiæ (Latin for "The Chronicle of the Prussian Land") is a chronicle of the Teutonic Knights, by Peter of Dusburg, finished in 1326. The manuscript is the first major chronicle of the Teutonic Order in Prussia and the Grand Duchy of Lithuania, completed some 100 years after the conquest of the crusaders into the Baltic region. It is a major source for information on the Order's battles with Old Prussians and Lithuanians.
