Maria of Calabria, Countess of Alba, was a Neapolitan princess of the Capetian House of Anjou whose descendants inherited the crown of Naples following the death of her older sister, Queen Joanna I.

The Capetian House of Anjou, or House of Anjou-Sicily, or House of Anjou-Naples was a royal house and cadet branch of the Capetian dynasty. It is one of three separate royal houses referred to as Angevin, meaning "from Anjou" in France. Founded by Charles I of Anjou, the youngest son of Louis VIII of France, the Capetian king first ruled the Kingdom of Sicily during the 13th century. The War of the Sicilian Vespers later forced him out of the island of Sicily, which left him with the southern half of the Italian Peninsula, the Kingdom of Naples. The house and its various branches would go on to influence much of the history of Southern and Central Europe during the Middle Ages until it became extinct in 1435.
