This article explores native speakerism, a chauvinistic ideology, in reference to relevant literature. It first exposes its ideological essence and adverse effects on English language teaching (ELT), and then moves to deconstruct the native speakerist practices concerning English language teachers, English language norm, cultural foundation of ELT curriculum, and teaching methodology, particularly the approaches of communicative language teaching (CLT) and task-based language teaching (TBLT). Through unearthing the culturist essence of native speakerism and the fallacies embedded in native speakerist ELT practices, this study is intended to contribute to eliminating native speakerism and building up more equitable and harmonious ELT profession.
