Holy Innocents' High School (Abbreviation: HIHS; Simplified Chinese:圣婴中学, Traditional Chinese: 聖嬰中學, pinyin: Shèngyīng Zhōngxué) is one of the earliest Catholic schools in Singapore. Founded in 1892 as a boys' school, the Chinese mission school has grown and expanded over the years and continues to provide secondary school education leading up to a Singaporean GCE 'O' Level certification, in both express and normal(academic) streams. The normal (technical) stream students will only take the GCE 'N' levels. Every year during Thanksgiving Day, the students and teachers attend thanksgiving mass and award ceremonies in the hall.
