Tryon's Raid occurred in July 1779, during the American Revolutionary War, in which 2700 men, led by British Major General William Tryon, raided the Connecticut ports of New Haven, Fairfield, and Norwalk. They destroyed military and public stores, supply houses, and ships as well as private homes, churches, and other public buildings. The raids were ineffectually resisted by militia forces.

The raid was part of a larger strategy designed by the British commander-in-chief, Lieutenant General Sir Henry Clinton, to draw Major General George Washington's Continental Army to terrain on which it might be more effectively engaged. The strategy failed, and both sides criticized General Tryon for the severity of his action. Although the raid had economic ramifications and affected military supplies, Clinton's efforts had no long-term strategic impact.
