The Kuomintang of China (/ˌkwoʊmɪnˈtɑːŋ/ or /-ˈtæŋ/; KMT, or Guomindang (/ˌɡwoʊmɪnˈdɑːŋ/) and GMD by its Pinyin transliteration, also translated as the Chinese Nationalist Party) has historically been the ruling political party of the Republic of China on the island of Taiwan; however, following losses in the presidential and legislative elections of 2016, the party will become the official opposition.

The predecessor of the KMT, the Revolutionary Alliance, was one of the major advocates of the overthrow of the Qing Dynasty and the establishment of a republic. The KMT was founded by Song Jiaoren and Sun Yat-sen shortly after the Xinhai Revolution of 1911. Sun was the provisional president but he did not have military power and ceded the first presidency to the military leader Yuan Shikai. After Yuan's death, China was divided by warlords, while the KMT was able to control only part of the south. Later led by Chiang Kai-shek, the KMT formed the National Revolutionary Army and succeeded in its Northern Expedition to unify much of China in 1928. It was the ruling party in mainland China from 1928 until its retreat to Taiwan in 1949 after being defeated by the Communist Party of China (CPC) during the Chinese Civil War. In Taiwan, the KMT continued as the single ruling party until the reforms in the late 1970s through the 1990s loosened its grip on power. Since 1987, the Republic of China is no longer a single-party state; however, the KMT remains one of the main political parties.

The guiding ideology is the Three Principles of the People, advocated by Sun Yat-sen. Its party headquarters are located in Taipei. The KMT is a member of the International Democrat Union. The previous president, Ma Ying-jeou, elected in 2008 and re-elected in 2012, was the seventh KMT member to hold the office of the presidency.

Together with the People First Party and Chinese New Party, the KMT forms what is known as the Taiwanese Pan-Blue Coalition, which supports eventual unification with the mainland. However, the KMT has been forced to moderate its stance by advocating the political and legal status quo of modern Taiwan. The KMT accepts a "One China Principle" – it officially considers that there is only one China, but that the Republic of China rather than the People's Republic of China is its legitimate government under the 1992 Consensus. However, since 2008, in order to ease tensions with the PRC, the KMT endorses the "three noes" policy as defined by Ma Ying-jeou – no unification, no independence and no use of force.
