Aurora (Russian: Авро́ра, tr. Avrora; IPA: [ɐˈvrorə]) is a 1900 Russian protected cruiser, currently preserved as a museum ship in St. Petersburg. Aurora was one of three Pallada-class cruisers, built in St. Petersburg for service in the Pacific Far East. All three ships of this class served during the Russo-Japanese War. The Aurora survived the Battle of Tsushima and was interned under U.S. protection in the Philippines, eventually returned to the Baltic Fleet. The second ship, Pallada, was sunk by the Japanese at Port Arthur in 1904. The third ship, Diana, was interned in Saigon after the Battle of the Yellow Sea. One of the first incidents of the October Revolution in Russia took place on the cruiser Aurora.

During World War I Aurora operated in the Baltic Sea performing patrols and shore bombardment tasks. In 1915, her armament was changed to fourteen 152 mm (6 in) guns. At the end of 1916, she was moved to Petrograd (the renamed St Petersburg) for a major repair. The city was brimming with revolutionary ferment and part of her crew joined the 1917 February Revolution. A revolutionary committee was created on the ship, with Aleksandr Belyshev elected as captain. Most of the crew joined the Bolsheviks, who were preparing for a Communist revolution.
At 9.45 p.m on 25 October 1917 (O.S.) a blank shot from her forecastle gun signaled the start of the assault on the Winter Palace, which was to be the beginning of the October Revolution. In summer 1918, she was relocated to Kronstadt and placed into reserve.
