Rear-Admiral Sir Hovenden Walker (1656 or 1666 – 1725 or 1728) was a British naval officer noted for, during Queen Anne's War, having led an abortive 1711 expedition against Quebec City, then the capital of New France.

In 1701 he joined the fleet under Sir George Rooke at Cadiz, and shortly afterwards, as commodore, took command of a detachment charged with cooperating in an attack on Guadeloupe and Martinique, which was unsuccessful.

[2] On 30 July, the expedition consisting of nine ships of war, two bomb vessels and 60 transports and tenders, British and colonial, with some 7,500 troops and marines aboard set sail from Boston.

On the morning of 18 August, just as the expedition was about to enter the Saint Lawrence River, the wind began to blow hard from the northwest, and Walker was forced to seek shelter in Gaspé Bay.

On the morning of the 20th, the wind veered to the southeast, and he was able to advance slowly past the western extremity of Anticosti Island before it died down and thick fog blanketed both shore and fleet.

When a captain reported that land had been sighted, presumably dead ahead, Walker assumed that he was approaching the south shore, and ordered the fleet to wear, and bring-to on the other tack.
