The National Tainan First Senior High School (Chinese: 國立臺南第一高級中學; pinyin: Guólì Táinán Dìyī Gāojí Zhōngxué) is a public senior high school in East District, Tainan, Taiwan.

It was established in 1922 and is considered one of the most prestigious high schools in Taiwan,[1] usually only accepting students who rank in the top 3 percentage of the Taiwan Basic Scholastic Test.

[2] After the war, Taiwan was handed to the Republic of China, whose high school system was a 3-3-year one.

The campus became independent in 1966 and was renamed to National ShinHua Senior High School.

[2] After Tainan was no longer included in Taiwan Province, the school became nationally funded.
