The primary aim of current study was to investigate the possible relationship between Metacognitive Awareness (MA) and Critical Thinking Skills (CTS) in a foreign language learning context. In addition, this research aimed to probe the effect of gender and years of pre-service English language teachers on the relation between metacognitive awareness and critical thinking abilities. 218 pre-service EFL (English as a Foreign Language) teachers participated in the study. Metacognitive Awareness Inventory and Critical Thinking Questionnaire were employed to gather necessary data. Obtained results confirmed that there existed a highly significant positive correlation between MA and CTS. Besides, the results indicated that there was a strong relation between the years of pre-service EFL teachers and their MA and CTS. Seniors were found to be more metacognitively aware and critical thinkers than their counterparts. Conversely, it was revealed that there was no gender effect on both MA and CTS. Finally, certain suggestions were set for tertiary institutions to develop metacognition and critical thinking skills in foreign language classroom settings.
