The widespread popularity of social media networks has encouraged learners to use them for learning purposes. Therefore, this study aimed to investigate the overall Saudi EFL learners' attitudes towards the use of Instagram as a language learning tool. It also examined the effect of gender on learners' attitudes. The study was conducted among 120 male and female EFL learners at Qassim University using a questionnaire. The results revealed that subjects had relatively positive attitudes toward the use of Instagram as a language learning tool. The results also indicated that there are no significant differences between male and female EFL learners in terms of their attitudes towards the use of Instagram as a language learning tool. The study concluded with implications related to how Instagram should be used as a supportive tool in English language teaching and learning.
