National Chiao Tung University (NCTU) was a public university in Hsinchu, Taiwan. Established in 1896 as Nanyang Public School by an imperial edict of the Guangxu Emperor, it was one of China's leading universities. After the Chinese Civil War, NCTU was re-established by former Chiao Tung University faculty and alumni in Taiwan in 1958.

NCTU was merged with National Yang-Ming University into the newly formed National Yang Ming Chiao Tung University on 1 February 2021.
