Self-regulation of learning has been extensively investigated in second language (L2) learning. Many studies have focused on the strategies that language learners employ to regulate their own learning processes. However, motivational self-regulation is considerably less explored. The aim of this study was to investigate the relationship between motivational self-regulatory strategies (MSRSs) and academic achievement. A motivational self-regulation questionnaire was administered to 64 male and female adult Iranian EFL learners to measure their choice of various strategies. The quantitative data was analyzed by applying correlational and multivariate analyses. The results demonstrated that there was a strong relationship between motivational self-regulatory strategy use and academic achievement. However, no difference was found between male and female learners in their use of the strategies. Further examination revealed that higher-achieving students differed from lower-achieving participants in their preference for strategies. The article concludes that while all learners use extrinsic rewards to self-regulate their motivation, more successful learners tend to manipulate learning tasks to make the tasks intrinsically interesting and pleasant. Also, more successful learners set both long-term and short-term goals to motivate themselves. The results underscore the importance of students’ personal interests, needs and goals, and suggest that teachers foster learners’ command of the strategies through instruction and cooperative activities.
