The British occupation of Manila was an episode in colonial history of the Philippines when the Kingdom of Great Britain occupied the Spanish colonial capital of Manila and the nearby port of Cavite for eighteen months, from the 6th October 1762 to the first week of April 1764. The occupation was an extension of the larger Seven Years' War between Britain and France, which Spain had recently entered on the side of the French.

Manila, officially the City of Manila, is the capital and second-most-populous city of the Philippines. Located on the eastern shore of Manila Bay on the island of Luzon, it is classified as a highly urbanized city. As of 2019, it is the world's most densely populated city proper. It was the first chartered city in the country, and was designated as such by the Philippine Commission Act No. 183 on July 31, 1901. It became autonomous with the passage of Republic Act No. 409, "The Revised Charter of the City of Manila", on June 18, 1949. Manila is considered to be part of the world's original set of global cities because its commercial networks were the first to extend across the Pacific Ocean and connect Asia with the Spanish Americas through the galleon trade; when this was accomplished, it was the first time an uninterrupted chain of trade routes circling the planet had been established.
