With the research on fostering and cultivating learner autonomy in foreign/second language teaching and learning, teacher autonomy has gained momentum in the research of foreign language teacher education. There have been many theoretical research and discussions about the definitions of learner autonomy. Many researchers acknowledge that language teachers play important roles in developing learner autonomy. However, the relationship between teacher autonomy and learner autonomy needs to be explored. The focal point of the present paper is a tentative discussion on the relationship between teacher autonomy and learner autonomy in foreign language education and teacher education. This paper sheds light to foreign language education and teacher education in that language teachers should change their traditional roles to ones catering and facilitating the development of learner autonomy, and teacher education and training programs should include and design courses, practicum to enhance and promote teacher-learner autonomy.
