The South China Sea raid (designated Operation Gratitude) was an operation conducted by the United States Third Fleet between 10 and 20 January 1945 during the Pacific War of World War II. The raid was undertaken to support the liberation of Luzon in the Philippines, and targeted Japanese warships, supply convoys and aircraft in the region.

After attacking airfields and shipping at Formosa and Luzon, the Third Fleet entered the South China Sea during the night of 9–10 January. Aircraft flying from its aircraft carriers attacked Japanese shipping off French Indochina on 12 January, sinking 44 vessels. The fleet then sailed north and attacked Formosa again on 15 January. Further raids were conducted against Hong Kong, Canton and Hainan the next day. The Third Fleet departed the South China Sea on 20 January and, after making further attacks on Formosa and the Ryukyu Islands, returned to its base on 25 January.

The Third Fleet's operations in the South China Sea were highly successful. It destroyed many Japanese ships and aircraft, while losing relatively few of its own aircraft. Historians have judged the destruction of cargo vessels and oil tankers to have been the most important result of the raid, as these losses contributed to closing a supply route which was vital to the Japanese war effort. Subsequent attacks by Allied aircraft and warships forced the Japanese to cease sending ships into the South China Sea after March 1945.
