Aurora (Russian: Авро́ра, romanized: 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.

Soon after completion, on 10 October 1903, Aurora departed Kronstadt as part of Admiral Virenius's "reinforcing squadron" for Port Arthur. While in the Red Sea, still en route to Port Arthur, the squadron was recalled back to the Baltic Sea, under protest by Admiral Makarov, who specifically requested Admiral Virenius to continue his mission to Port Arthur. Only the seven destroyers of the reinforcing squadron were allowed to continue to the Far East.

After her detachment from the reinforcing squadron and her arrival back to home port she underwent new refitting. After refitting, Aurora was ordered back to Port Arthur as part of the Russian Baltic Fleet Aurora sailed as part of Admiral Oskar Enkvist's Cruiser Squadron whose flagship would be the protected cruiser Oleg, an element of Admiral Zinovy Rozhestvensky's Baltic Fleet. On the way to the Far East, Aurora received five hits, sustaining light damage from confused friendly fire, which killed the ship's chaplain and a sailor, in the Dogger Bank incident.

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.

The ship's commanding officer, Captain Mikhail Nikolsky, was killed when he tried to suppress the revolt.

In 1922, Aurora returned to service as a training ship.

During the Second World War, her guns were taken from the ship and used in the land defence of Leningrad. The ship herself was docked in Oranienbaum port, and was repeatedly shelled and bombed. On 30 September 1941, she was damaged and sunk in the harbour.

She was later salvaged and repaired after the war.

The ship was opened as a museum ship in Leningrad in 1957, as a monument to the October Revolution.

After having served as a museum ship for 27 years, from 1984 to 1987 the cruiser was once again placed in her construction yard, the Admiralty Shipyard, for capital restoration. During the overhaul, due to deterioration, the ship's hull below the waterline was replaced with a new welded hull according to the original drawings. The cut off lower hull section was towed into the Gulf of Finland to the decommissioned Ruchi Naval Base [ru], and sunk near the shore. The restoration revealed that some of the ship's parts, including the armour plates, were originally made in Britain.

In January 2013, Russian Defence Minister Sergey Shoygu announced plans to recommission Aurora and make her the flagship of the Russian Navy due to her historical and cultural importance. On 21 September 2014, the ship was towed to the Admiralty Shipyard in Kronstadt to be overhauled, to return in 2016. On 16 July 2016, she returned to her home harbour in Saint Petersburg.

The 1965 Soviet film The Salvos of the Aurora Cruiser shows the ship's action in the October Revolution.

In 1973, a short film about the ship, titled Aurora, was released.
