The Presidential Office Building is the work place of the president of the Republic of China on Taiwan. The building, located in the Zhongzheng District in the national capital — Taipei, was designed by architect Uheiji Nagano during the period of Japanese rule of Taiwan (1895–1945). The structure originally housed the Office of the Governor-General of Taiwan. Damaged in Allied bombing during World War II, the building was restored after the war by Chen Yi, the governor-general of Taiwan Province. It became the Presidential Office in 1950 after the government of the Republic of China lost control of mainland China and relocated the nation's capital to Taipei at the end of the Chinese Civil War. At present, this Baroque-style building is a symbol of the government and a famous historical landmark in downtown Taipei.

The president of the Republic of China, commonly known as the president of Taiwan, is the head of state of the Republic of China (Taiwan) as well as the commander-in-chief of the Republic of China Armed Forces. The position once had authority of ruling over Mainland China, but its remaining jurisdictions has been limited to Taiwan, Penghu, Kinmen, Matsu, and other smaller islands since the conclusion of the Chinese Civil War.
