HMS Galatea was an Arethusa-class light cruiser launched on May 14, 1914 at Beardmore shipyard.

At the battle of Jutland, she was the flagship of the First Light Cruiser Squadron under Commodore E.S. Alexander-Sinclair. She was the first ship to report the presence of German ships, triggering the battle.

Galatea was part of the screen around the Battle Cruiser Force under Admiral Beatty which was on a sweep across the North Sea on May 31, 1916. She was sent in company with HMS Phaeton to investigate a stopped merchant vessel, the Danish N J Fiord. At the same time, two destroyers B-109 and B-110 from the German battlecruiser and cruiser Scouting Groups under Admiral Franz von Hipper were sent to investigate the ship. The two fleets were previously unaware that they were less than 50 miles apart.

She was sold for scrapping in October, 1921.
