Peter II (Latin: Petrus, Italian: Pietro, Sicilian: Pietru; 1304 – 8 August 1342) was the King of Sicily from 1337 until his death, although he was associated with his father as co-ruler from 1321.

Peter's father was Frederick III of Sicily and his mother was Eleanor, a daughter of Charles II of Naples.

[1] His reign was marked by strife between the throne and the nobility, especially the old families of Ventimiglia, Palizzi and Chiaramonte, and by war between Sicily and Naples.

[2] Under Peter, the Neapolitans conquered the Lipari Islands and took the cities of Milazzo and Termini in Sicily itself.

[2] He died after a short illness on 8 August 1342[2] in Calascibetta and was buried in the cathedral of Palermo.
