Dietrich IV, Landgrave of Lusatia, also called Diezmann, or Dietrich III (c. 1260 – probably 10 December 1307 in Leipzig) was a member of the House of Wettin. He was Margrave of Lusatia from 1291 to 1303. He was also Margrave of Osterland from 1291 until his death, and Landgrave of Thuringia, as Dietrich I, from 1298 until his death.
After Dietrich's mother fled from the Wartburg in 1270, because her husband had fallen in love with Kunigunde of Eisenberg, Dietrich and his elder brother Frederick I were raised by their uncle Margrave Theodoric of Landsberg. After Dietrich and Frederick had come of age, they and their elder brother Henry fought a war against their father, who wanted his son Apitz from his second marriage with Kunigunde, to inherit the Landgraviate of Thuringia.
In 1301 Archbishop Burchard II of Magdeburg sold him the castles in Droyßig and Burgwerben for 2000 mark of Stendal silver, with the option to buy them back later. Burchard did not use this option; instead he also sold the castle and town of Spremberg to Dietrich.
Adolph of Nassau, the King of the Romans, deprived Dietrich of his inherited lands. After Adolph's fall, Dietrich was reinstated. In 1307, King Albert I of Germany invaded the Osterland with a large army. Dietrich and Frederick armed civilians and peasants and with some assistance from knights from Brunswick, they defeated Albert in the Battle of Lucka on 31 May 1307.
Dietrich died in December 1307 in Leipzig. According to later traditions, he was murdered on 24 or 25 December by one Philip of Nassau in the St. Thomas church in Leipzig. However, it is more probably that he died of natural causes on 10 December.
Dietrich married in 1295 to Jutta, the daughter of Count Berthold VIII of Henneberg. This marriage did not produce an heir.
