Chinese Pinyin (Chinese phonetic alphabets, Chinese Pinyin) is the romanization system for Chinese characters developed between 1955 and 1957 by the Chinese Romanization Committee (now the National Language Committee of China) during the script reform period. This system is mainly used to mark the pronunciation of Mandarin Chinese, serving as a phonetic notation for Chinese characters.

On February 11, 1958, the National People's Congress officially approved and announced the Pinyin system. In 1982, it became the international standard ISO 7098 (Romanization of Chinese). Some overseas Chinese communities, such as those in Singapore, have adopted Pinyin in Chinese language education.

In September 2008, the Taiwan region of China decided to replace the "Tongyong Pinyin" system with "Hanyu Pinyin" as the standard for Chinese-to-English transliteration, which took effect in 2009.

Hanyu Pinyin serves as a tool to assist in the pronunciation of Chinese characters.
