Ruben II (), also Roupen II or Rupen II, ( 1165–1170) was the seventh lord of Armenian Cilicia (1169âÂÂ1170).
Roupen was the son of Thoros II, lord of Armenian Cilicia, by his second wife (and great niece) whose name is unknown. (Thomas was the childâÂÂs maternal grandfather). However, Thoros IIâÂÂs brother, Mleh disputed the succession; Mleh had fled to Nur ad-Din (the emir of Aleppo) and become a Muslim after quarreling with Thoros II and attempting to assassinate him.
