HMS Tiger or Tygre was a 60-gun fourth rate ship of the line of the Royal Navy, built at Rotherhithe to the draught specified by the 1745 Establishment and launched on 23 November 1747.

[1] Tiger was commissioned in December 1747 under Captain Charles Saunders, as a reinforcement for the British fleet then in action against France in the War of the Austrian Succession.

The war ended with the signing of the Treaty of Aix-la-Chapelle in April 1748, and Tiger was returned to Deptford for service as a guard ship.

[2] In the British anti-piracy campaign of 1756 HMS Kent, Kingfisher, and Tiger carried 300 Indo-Portuguese Topazes to capture the fortress of Gheriah on 14 February 1756.

[4] In order to take the Fort d'Orleans guarding the town, Tiger and Kent managed to edge up the Hooghly river, although the French had tried to block it with sunken ships, booms and chains.
