This research intends to explore the efficacious English teachers’ goals and strategies to effectively manage their own as well as their students’ emotions. The data of the study included interviews with 22 English teachers and 92 diary journals kept by 12 teachers who were among the top 20% of ELTEI (ELT teacher efficacy instrument) scorers and identified as efficacious English teachers. The results indicated that teachers’ goals for regulating their positive emotions included maintaining authority in relation to students, presenting unbiased teacher character, and enhancing teaching effectiveness. For regulating negative emotions, the goals included maintaining the teacher and students’ mental health, promoting teacher-student relationships, and reinforcing the image of teachers as moral guides. Teachers also used a variety of antecedent-focused and response-focused strategies hierarchically for effective emotion management including situation selection, situation modification, attention deployment, cognitive change, and response modulation. The findings were discussed with reference to the role of culture in emotion regulation and effectiveness of different sub-strategies. The results may promise some implications for teacher education programs and teacher educators about the inclusion of professional development opportunities for EFL teachers in terms of effective emotion management
