Taipei Municipal Datong High School (DTHS in Hanyu Pinyin, originally TTSH in Wade-Giles: Taipei Municipal Ta Tung Senior High School, Traditional Chinese: 臺北市立大同高级中學) is a public senior high school in Taipei, Taiwan.

Taipei Municipal Datong High School was established in 1935 as a combined junior and senior high school. In 1968, authorities implemented a nine-year compulsory education for Taiwan. This change made Datong a junior high school. Following the authorities’ educational policy, in 1992, the system of the school was changed into a high school. The senior high school was added to the junior high school. Datong High School returned to its origins of 1935 and became the first complete high school in the country.

By order of the government, the school started evening sessions in 1953, which stopped enrolling new students in 1981. The evening sessions terminated two years later after the final students in the programme graduated.

The area of DTHS is about 69,000 square meters. It is the largest campus of municipal high schools in Taipei City. The scheme of the campus blends Chinese traditional structure and Western European classical style. There are Long Chi (Dragon Pond), Feng Yuan (Phoenix Garden), Zhisheng Yuan (Confucius Garden), Zhicheng Yuan (Sincerity Garden), and Zhishan Yuan (Perfection Garden) on campus. Datong was praised as the best school building of Taiwan by the National Association of Architects in 1994.
