Dietrich VIII (c. 1291 – 7 July 1347) was Count of Cleves from 1310 until his death in 1347.^[1]

Dietrich was the son of Dietrich VII, Count of Cleves and his second wife Margaret of Habsburg. He succeeded in 1310 his half-brother Otto, Count of Cleves who had died without sons.

Dietrich VIII married twice:

• Margaret of Guelders († 1333), daughter of Reginald I of Guelders, in 1308. They had two daughters:
  • Margaret († 1341), married in 1332 Adolph II of the Marck († 1347), had issue.
  • Elisabeth (1307–1382), married Gerard of Voorne and Otto II of Hesse.
• Maria of Jülich († 1353), daughter of Gerhard V of Jülich, in 1340. They had another daughter:
  • Maria, unmarried, no issue

He was succeeded by his brother John.
When his brother also died without a son, the County of Cleves went to his daughter's son Adolph III of the Marck and so to the Counts of Marck.
