Objective: The present study aims to explore the relationship between EFL students' intercultural contact through social networking sites and their L2 motivation. Method: To do so, a number of 162 university students participated in answering three sets of questionnaires. A regression analysis identified correlations between L2 motivation and intercultural engagement through social networking sites during the learning process. Results and Discussion: Instagram and YouTube were determined to be the primary sources of intercultural contact among Indonesian EFL students. The study also revealed a substantial relationship between intercultural contact, the L2 motivational self-system, and its constituents. Originality/Value: Based on the findings, this study suggests that teachers employ social networking sites as often as possible in classroom activities to engage students with meaningful learning in their target language.
