Benedetto Brin was an Italian naval administrator and politician. He played a major role in modernizing and expanding the Italian Regia Marina from the 1870s to the 1890s, designing several major classes of warships, including the large ironclad warships of the Duilio, Italia, and Re Umberto classes, the pre-dreadnought battleships of the Ammiraglio di Saint Bon and Regina Margherita classes, and the armored cruisers of the Vettor Pisani and Giuseppe Garibaldi classes. His contributions to Italian naval power were marked by the naming of the second Regina Margherita-class battleship as Benedetto Brin, among other commemorations.

The Regina Margherita class was a class of two battleships built for the Italian Regia Marina between 1898 and 1905. The class comprised two ships: Regina Margherita and Benedetto Brin. The ships were designed by the latter's namesake, Benedetto Brin, who died before the ships were completed. They were armed with a main battery of four 12 in (305 mm) guns and could steam at a speed of 20 knots.
