This study is intended to examine the relationship between critical thinking disposition and English learning achievement among Iranian high school third-grade EFL learners mediated by emotional intelligence. A sample of 264 students (145 males and 119 females) was assessed for their level of critical thinking disposition and emotional intelligence. Participant's scores on their final English test were also used as the measurement of their English achievement. The results revealed a positive correlation between total critical thinking dispositions (r=.506, p<.01) and its subscales i.e., engagement(r=.33), maturity(r=47), and innovativeness (r=44.6) with English learning achievement. The results also suggested that emotional intelligence acts as a mediator of the relationship between critical thinking disposition and English learning achievement.
