This paper discusses ethics issues in Korean language education. To this end, first, I looked at issues of education and ethics. Then, I examined the study of ethics education in the Korean language education from the past to the present and the implementation of the ethics education. Finally, we looked at the characteristics of future society and discussed the issue of Korean language education and ethics in future society. As a result of the discussions, education is ethical in nature, and ethics education has been carried out either partially or wholly in Korean language education. In the future society, communication between human beings and human beings, human beings and machines is essential, so that the ethics of language use emerges as a more important problem. Therefore, it was found that ethics education should be strengthened in Korean language education of future society. We hope that the discussion in this paper will be used in the actual education field to help the ethics education in Korean language education.
