The ARA Veinticinco de Mayo was a cruiser which served in the Argentine Navy through World War II. The English translation of the name is May 25, which is the date of Argentina's May Revolution in 1810.

The Veinticinco de Mayo was built in Italy and was the first ship of the Veinticinco de Mayo class of cruisers. Three vessels were to be produced, but in the end, only 25 de Mayo and her sister ship Almirante Brown were acquired, both in 1931.

These ships were unusual in several ways. First, they carried 7.5 inch guns, only the third class of warship to do so. Also, like the Italian Zara class and other Italian-built warships of the era they carried their floatplanes under the foredeck and launched them from a fixed catapult over the bows.
