This study aims to explore language learning beliefs of Korean language learners from three different levels of proficiency and then compare their beliefs with those of language teachers who are native speakers of Korean. A total of 126 participants (ninety nine students and 27 teachers) were asked to fill out a questionnaire, the Beliefs about Language Learning Inventory (BALLI). The findings show that the students from the three levels of proficiency hold many similar beliefs on language learning, but they also hold some different beliefs. The analysis of an ANOVA and a Post-hoc revealed that the mean differences for certain items were statistically significant among the three groups. Also, the findings revealed that the students and the teachers maintain different beliefs, and the analysis of a t-test for the two groups showed that some differences between the two groups are statistically significant. These findings yield some points for teachers to contemplate with a view to promoting students motivation and language learning
