This study tried to investigate the impact of task-based instruction (TBI) on the enhancement of Iranian EFL learners’ speaking skill. The study also tried to scrutinize the impact of TBI on learners’ emotional intelligence. To meet these ends, 60 students were randomly divided into two groups, the experimental group and the control group. At the very first session of the term, two speaking examinations were conducted for both experimental and control group. After the speaking examinations, the participants were asked to answer Bar-On’s emotional intelligence questionnaire. The experimental group was instructed through task-based approach and the control group received instruction through present-practice-produce (PPP) approach. The scores obtained by two raters from the interview post-tests were analyzed through non-parametric tests, and the data obtained from EQ questionnaires were analyzed through t-tests. Results of the statistical analysis revealed that the experimental group performed significantly better on the speaking post-test than the control group. Furthermore, the findings also indicated that the learners in the experimental group became more emotionally intelligent than those in the control group.
