This research aims to identify the correlation between metacognition and emotion regulation among pre-service teachers. 238 pre-service teachers from an Institute of Teacher Education responded to Metacognitive Awareness Inventory (MAI) and Emotion Regulation Questionnaire (ERQ). Based on the result, there is a significant correlation (r=0.328) between metacognition and emotion regulation among pre-service teachers. Teacher education should focus on pre-service teachers’ metacognitive development to improve emotion regulation.
