The action of 6 November 1794 was a naval engagement during the French Revolutionary Wars. Two British ships of the line, HMS Alexander and HMS Canada were intercepted while returning to Britain through the Celtic Sea by a large French squadron. The French squadron had sailed from Brest in search of an inward bound British convoy in October, but instead encountered the two British ships returning from escorting an outward-bound convoy. There had been no warning of the French approach as the British force assigned to watch Brest was absent at Plymouth due to the policy of operating a distant blockade.

HMS Alexander was a 74-gun third-rate of the Royal Navy. She was launched at Deptford Dockyard on 8 October 1778. During her career she was captured by the French, and later recaptured by the British. She fought at the Nile in 1798, and was broken up in 1819. She was named after Alexander the Great.
