The "National Anthem of the Republic of China", also known by its incipit "Three Principles of the People", is the national anthem of the Republic of China, commonly called Taiwan, as well as the party anthem of the Kuomintang. It was adopted in 1930 as the national anthem and was used as such in mainland China until 1949, when the Republic of China central government relocated to Taiwan following its defeat by the Chinese Communist Party in the Chinese Civil War. It replaced the "Song to the Auspicious Cloud", which had been used as the Chinese national anthem before. The national anthem was adopted in Taiwan on October 25, 1945 after the surrender of Imperial Japan. Mainland China, being governed by the People's Republic of China today, discontinued this national anthem for "March of the Volunteers".

The national anthem's words are adapted from a 1924 speech by Sun Yat-sen in 1937. The lyrics relate to how the vision and hopes of a new nation and its people can be achieved and maintained. Informally, the song is sometimes known as "San Min Chu-i" from its opening line, which references the Three Principles of the People (三民主義; sānmín zhǔyì; san1-min2 chu3-i4), but this name is never used on formal or official occasions. During flag-raising ceremonies, the national anthem is played at the start prior to flag-raising followed by the National Flag Anthem of the Republic of China during actual flag-raising.
