Metacognitive teaching holds an essential role today since it facilitates the development of lifelong learning skills and prepares students for their professional careers. It is crucial to show if metacognition is strongly related to epistemological beliefs, this influencing how teachers use various teaching strategies and are in tune with their students' learning process. This research sheds light on how metacognition relates to epistemological beliefs in the educational context and aims to find the relationship between these two variables and test the predictive role of epistemological beliefs on metacognition. Two selfreported instruments on a five-point Likert scale were completed by 146 pre-university teachers, who took part in our online investigation. Metacognition used in teaching practices was measured with The Metacognitive Awareness Inventory for teachers and teachers' epistemological beliefs with The Epistemological Questionnaire Beliefs Inventory. Data analysis included specific demographic characteristics such as age, teaching experience, teaching level, specialization, job type, and teaching degrees, which were related to both epistemological beliefs and metacognitive awareness. In terms of the relationship between epistemological beliefs and metacognitive awareness, a strong predictive model has been revealed: epistemological beliefs are a strong predictor of metacognitive awareness. The findings are analysed in relation to their practical implications.
