The Sovereign Prince of Monaco is the sovereign monarch and head of state of the Principality of Monaco. All Princes thus far have belonged to the House of Grimaldi; the current Prince Albert II.

Titles and styles

Like all Monegasque royalty, the Prince is styled His Serene Highness (or, in the case of a ruling Princess, Her Serene Highness). Though they are rarely used, the Prince also bears a great many other hereditary titles, some of which are occasionally bestowed on his relatives or their spouses. Most of these titles have merged with the Crown of Monaco as a result of the Grimaldi family's acquisition of various duchies, counties, baronies, and other fiefs, though they are almost all extinct and carry no administrative power. The current Prince's complete titles and styles are:
