Teachers' beliefs about teaching character values are pivotal in cultivating students' character. This study systematically reviewed teachers' beliefs towards character education in primary school. A systematic review following the PRISMA statement was applied to peer-reviewed papers published between 2011 and 2021. This review paper analyzed three main themes based on three research questions, namely, (1) teachers' beliefs of character education curriculum, (2) beliefs of values, and (3) pedagogical beliefs. Findings revealed that teachers mostly believed in an integrated character education curriculum with role model pedagogy. Moreover, there were seventeen (17) values teachers believed to instil which respect and responsibility were the two most dominant values to foster. This study implies that teachers' beliefs are significant factors in proper character education curriculum implementation. This study also provides significant implications for policymakers and curriculum designers in developing a character education curriculum that meets teachers' beliefs.
