Blackwall was a 50-gun fourth-rate ship of the line of the English Royal Navy, one of four ordered in September 1694 (Blackwall and Guernsey on 12 September and Nonsuch and Warwick on 25 September) to be built by commercial contracts; eight further ships of this type were ordered on 24 December (six to be built by contract and two in Royal Dockyards).

[1] In September 1705, whilst under the command of Captain Samuel Martin, the Blackwall, along with two smaller vessels, had been ordered to convoy some merchantmen to the Baltic.

Both Captain Martin and the French commander were killed in the action.

[1][3] Blackwall was commissioned into the French Navy under the name Blekoualle; she was recaptured on 15 March 1708 but was not taken back into service in the Royal Navy, the decision being taken to have her broken up instead.
