The present study investigated the relationship between Iranian EFL learners’ use and preferences of language learning strategies and their meta-knowledge and the tasks of pragmatic competence. Quick Oxford Placement Test, version 2 (2004) was administered and 120 upper-intermediate EFL university students majoring in English translation and TEFL were recruited from the available branches of the Islamic Azad University, Fars province. Likewise, a questionnaire entitled Iranian EFL learners’ meta-knowledge and pragmatic tasks (2016) was used to explore EFL learners’ meta-knowledge and tasks of pragmatic competence and the mean score was calculated. Then, Oxford Strategy Inventory for Language Learning (1990) was used to analyze EFL learners’ use and preferences of language learning strategies and the mean score was calculated. Also, to examine any possible relationship between EFL learners’ use and preferences of language learning strategies and their meta-knowledge and pragmatic tasks, some correlations were run. The results of data analyses showed that Iranian EFL learners were moderate in meta-knowledge and tasks of pragmatic competence and in their use of language learning strategies in general. More detailed analyses of the data ranked the order of the applications of the strategies as: social strategies, meta-cognitive strategies, cognitive strategies, memory strategies, compensation strategies and affective strategies from the most to the least frequent strategies applied by the participants of the study. There was a significant medium positive relationship between meta-knowledge and tasks of pragmatic competence and meta-cognitive strategy. However, there were slight but significant positive relationships between meta-knowledge and tasks of pragmatic competence and compensation and affective strategies and no relationships between meta-knowledge and tasks of pragmatic competence and social, affective and compensation strategies.
