This paper seeks to examine how South Korea news medias portrayed mixed-race South Koreans in Korean society by checking articles from the newspapers Dong-A Ilbo and Kyunghyang Shinmun. The paper explores the process of formation of discourse on mixed-race in South Korea, and the contextual background that related to it by analysing about 800 newspaper articles from 1950 to 2019 through critical discourse analysis. The research is conducted within the theoretical frames of imagined community, the concept of ‘othering’, and race and ethnicity in the discourse analysis of the newspapers. The results of the study show that mixed-race people in South Korea are often stigmatised and discriminated for their difference in society as ‘others’ in the newspaper portrayals. Furthermore, the paper highlights that such portrayals of mixed race are based on ethnic nationalism and patriarchal ideas that influenced the discourse around them in South Korea.
