Conte di Cavour was the name ship of the three Conte di Cavour-class dreadnought battleships built for the Royal Italian Navy (Regia Marina) in the 1910s. Completed in 1915 she served during World War I, although she was little used and saw no combat. The ship supported operations during the Corfu Incident in 1923 and spent much of the rest of the decade in reserve. She was rebuilt between 1933 and 1937 with more powerful guns, additional armor and considerably more speed than before.
