HMS Severn was a 50-gun fourth rate ship of the line of the Royal Navy, launched at Blackwall Yard in 1695. On 13 May 1734, orders were issued for Severn to be taken to pieces and rebuilt at Plymouth according to the 1733 proposals of the 1719 Establishment. Severn was relaunched on 28 March 1739, and served until 1746, when she was captured.
