Abstract-Owing to the importance of teacher's impact on the students' motivation, achievement, and academic success, this study is an attempt to explore the relationship between EFL (English as a foreign language) teachers' spiritual intelligence and their level of efficacy. To this end, two questionnaires, the Spiritual Intelligence Self-Report Inventory (SIRI-24) (King, 2008), and the ELT Teacher Efficacy Instrument (ELTEI) (Akbari& Tavassoli, 2014), were distributed among 148 male and female EFL teachers working at different contexts including university, school, and private language institute in Mashad, Quchan, Shirvan, and Qaemshahr, Iran. Pearson product-moment correlation and an independent T-test were used for analysis of the data. The findings of the study revealed that there was a positive significant relationship between teacher spiritual intelligence and teacher efficacy. Moreover, there is a significant difference between male and female teachers regarding their personal meaning production.
