Peter II, called the Fat, was the eleventh King of Cyprus of the House of Lusignan from 17 January 1369 until his death. He was the son of Peter I of Cyprus and Eleanor of Aragon. He succeeded to the throne while he was still under age, following the assassination of his father in 1369. He was also titular Count of Tripoli and King of Jerusalem.

The Kingdom of Cyprus was a medieval kingdom of the Crusader states that existed between 1192 and 1489. Initially ruled as an independent Christian kingdom, it was established by the French House of Lusignan after the Third Crusade. It comprised not only the entire island of Cyprus, but it also had a foothold on the Anatolian mainland: Antalya between 1361 and 1373, and Corycus between 1361 and 1448.
