Dietrich III. von Katlenburg (* around 1075/80; † August 12, 1106 ) was the last count of Katlenburg. He presumably first used the Katlenburg , which was built in the 11th century, and later the Stauffenburg near the important mint in Gittelde as a mansion.

His parents were Dietrich II of Katlenburg and Gertrud the Younger of Braunschweig . After the murder of his father in 1085 he followed him as a count under the tutelage of his mother, through whom he stood in the anti-imperial camp.

After 1100 he married Adele von Northeim (* around 1090; † 1123; the daughter of Kuno von Northeim , Count of Beichlingen).

In the power struggle between Emperor Heinrich IV and his son (later Heinrich V ), Dietrich was on the side of the son.

In 1104 he attacked a delegation from the Magdeburg Church that was on the way to see Emperor Heinrich IV because of the ousting of Archbishop Heinrich von Magdeburg from his diocese and replacement of the Magdeburg Archbishopric. Among other things, he captured the imperial partisan Burgrave Hermann von Sponheim-Magdeburg and his nephew, Provost Hartwig von Magdeburg. Thereupon the emperor undertook a punitive expedition against Dietrich on November 30, 1104. It was canceled due to the events in Fritzlar when the emperor's son secretly left the camp. As a result of this punitive expedition, Henry V's rebellion against the emperor began.

In mid-June / early July 1106, King Heinrich besieged Cologne . Here Dietrich fell ill with a disease spreading among the siege troops. It is unclear whether he died here or not until August 12, 1106 in Aachen.

The heirless count had laid down his ancestral castle Katlenburg around 1105 and converted it into a monastery. Some sources that report his death refer to Dietrich III. consequently as Count von Einbeck , because the Count's court in Einbeck , which the ancestor of the Count of Katlenburg, Count Udo , had received, was linked to important rights.

With the extinction of the family, the Mecklenburg property came by inheritance to the Guelphs . His widow soon married Count Helperich von Plötzkau .
