Crystal Boys (孽子, pinyin: Nièzǐ, "sons of sin") is a novel written by author Pai Hsien-yung and first published in 1983 in Taiwan.

The story takes place in Taipei in 1971 (or, in the most recent film adaptation, in 1973), and follows a short period in the life of a young man called Li-Qing (李青, nicknamed A-Qing).

When A-Qing is expelled from his school because of "scandalous relations" with classmate Zhao Ying (趙英), his father kicks him out of the family home.

An English translation of the novel by Howard Goldblatt, titled Crystal Boys, was published in 1990 by Gay Sunshine Press.
