The Battle of Dungeness was a naval battle of the First Anglo-Dutch War fought on 10 December 1652 near the cape of Dungeness in Kent.

In October 1652 the government of the Commonwealth of England, mistakenly believing that the United Provinces had been defeated at the Battle of the Kentish Knock, sent away ships to the Mediterranean. This left the English badly outnumbered in home waters. Meanwhile the Dutch were making every effort to reinforce their fleet.

On 1 December 1652 Admiral Maarten Tromp set sail from Helvoetsluys with 88 men of war and 5 fire ships, escorting a vast convoy bound for the Indies. With the convoy safely delivered through the straits of Dover, Tromp turned in search of the English, and on 9 December 1652 he encountered the English fleet of 42 ships commanded by General-at-Sea Robert Blake. Bad weather prevented an action that day, but the next day Blake came out to fight and the two fleets met at about 15:00 near the cape of Dungeness in a "bounteous rhetoric of powder and bullet" (according to a contemporary account).

By nightfall the Dutch had sunk four ships, captured two, and damaged many more. Blake retreated under cover of darkness to his anchorage in the Downs.

The victory gave the Dutch control of the English Channel and so control of merchant shipping. A legend says that Tromp attached a broom to his mast as a sign that he had swept the sea clean of his enemies.

The battle not only showed the folly of dividing forces while the Dutch still possessed a large fleet in home waters, but exposed "much baseness of spirit, not among the merchantmen only, but many of the state's ships". It seemed that the captains of hired merchant ships were reluctant to risk their vessels in combat, while the state's ships lacked the men to sail and fight them.

Over the winter, Blake and the Commissioners of the Navy repaired the fleet, reviewed naval tactics and wrote the Sailing and Fighting Instructions , issued to commanders in 1653, and including the first descriptions of the line of battle tactic. By February 1653 the English were ready to challenge the Dutch control of the seas, resulting in the three-day Battle of Portland.
