Seleucus V - Basileus of Basileía tōn Seleukidōn from 126 BC to 126 BC
Seleucus V was the eldest son of Demetrius II Nicator and Cleopatra Thea, and ruled the Seleucid Empire for a short time in 126 BC.

Two different motives are given as reason for this deed: according to one version he had attempted to claim the throne without her agreement; according to the other version she was afraid that he might avenge the assassination of his father.
