Ammiraglio di Saint Bon was a pre-dreadnought battleship of the Regia Marina built during the 1890s. She was laid down in July 1893, launched in April 1897, and completed in May 1901. She was the lead ship of her class, and had one sister ship, Emanuele Filiberto. The ship was armed with a main battery of four 254 mm (10 in) guns and was capable of a top speed of 18 knots.

The Ammiraglio di Saint Bon class was a pair of pre-dreadnought battleships built for the Italian Navy during the 1890s. The class comprised two ships: Ammiraglio di Saint Bon, the lead ship, and Emanuele Filiberto. They were armed with a main battery of four 254 mm (10 in) guns and were capable of a top speed of 18 knots. Smaller and less powerfully-armed than most contemporary battleships, they marked a brief departure from Italian capital ship design, which had previously emphasized large ships equipped with large guns.
