種族主義（英語：Racism）指一套意識型態，其基本信仰為人類可以被分類成不同及互不附屬的“種族”實體，因此主張遺傳的肉體特質直接決定人性、智識、道德等等文化及行為的特性，并主張某種族在本質上比其他種族優越。racism, www.britannica.com 來源原文為any action, practice, or belief that reflects the racial worldview?the ideology that humans are divided into separate and exclusive biological entities called "races," that there is a causal link between inherited physical traits and traits of personality, intellect, morality, and other cultural behavioral features, and that some races are innately superior to others.種族主義做為意識型態則和研究人種或人群差異的科學及人文社會科學不同，做為意識型態的種族主義其種族決定論及特定種族優越的信仰是不容科學研究允許的不同結論及批判思考。
