The highly urbanized city of Manila is currently represented in the House of Representatives of the Philippines by its six congressional districts. Every three years, each district elects one representative who will sit on their behalf in Congress. In addition, each district is allotted six seats in the Manila City Council, with councilors being elected every three years.

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.
