Hethum (or Hetoum) II of Armenia (died 1307) was king of the Armenian Kingdom of Cilicia, ruling from 1289 to 1292, 1294 to 1297 and 1299 to 1307. He was the son of Leo III of Armenia and Kyranna de Lampron.

In 1292 Armenia was invaded by Khalil, the Mamluk sultan of Egypt, who had conquered the Kingdom of Jerusalem the year before. Later that year Hethum abdicated in favour of his brother Thoros III. After Thoros's death in 1298 at the hands of their brother Sempad, Hethum managed to regain the crown with the help of a fourth brother Constantine. Part of his reign was spent in the monastery at Mamistra.

Hethum married Helvis de Lusignan, the daughter of King Hugh III of Cyprus. Hethum's son Thoros, the Crown Prince, was murdered in 1296 by his brother Sempad.

In 1307 Hethum and his co-ruler, his nephew Leo IV, were murdered while visiting the Mongol emir Bilarghu at Navarza.
