This study sought to investigate the impact of world Englishes (WE) and English as a lingua franca (ELF) research on Hong Kong's ELT curricula and textbooks over the past four decades in three areas: (1) language standards, norms and models; (2) language and intercultural awareness; and (3) strategies for international communication. Based on qualitative and quantitative content analysis, the findings suggest that WE/ELF research has influenced Hong Kong's English language education mainly by accommodating to the changing role of English (from a colonial to international language) and the evolving language use contexts, but there has been little engagement with the pluricentric view of language varieties and variation. The paper offers suggestions to initiate changes that could better accommodate WE/ELF research in the gradual ELT development. Copyright ©Wiley-Blackwell Publishing Ltd.
