Aurora (Russian: Авро́ра, tr. Avrora, IPA: [ɐˈvrorə]) is a Russian protected cruiser, currently preserved as a museum ship in Saint Petersburg.

Aurora was one of three Pallada-class cruisers, built in Saint Petersburg for service in the Pacific. All three ships of this class served during the Russo-Japanese War. Aurora survived the Battle of Tsushima and was interned under US protection in the Philippines, and eventually returned to the Baltic Fleet.

One of the first incidents of the October Revolution in Russia took place on the cruiser Aurora, which reportedly fired the first shot, signalling the beginning of the attack on the Winter Palace.
