Taft Avenue is a major road in the south of Metro Manila. It passes through three cities in the metropolis: Manila, Pasay, and Parañaque. The road was named after the former Governor-General of the Philippines and U.S. President, William Howard Taft; the Philippines was a former commonwealth territory of the United States in the first half of the 20th century. The avenue is a component of National Route 170 (N170), a secondary road in the Philippine highway network and the entirety R-2 of the Manila arterial road network.

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.
