The current study aimed to investigate the effect of using Instagram and social media engagement techniques on developing EFL students' speaking skills (accuracy, fluency, pronunciation, and presentation). Forty students enrolled in Third year Faculty of education, Shebin Elkom, Menoufia University were the participants of this study. A sequential mixed methods design was used to collect data, thus in the first phase of the study, the researcher designed a pre-posttest for measuring EFL pre-service teachers' speaking skills (accuracy, fluency, pronunciation, and presentation), a scoring rubric to be used for grading students' performance on the test, a programme based on Instagram and social media engagement techniques and an intercultural awareness test. In Phase two, semi-structured interviews conducted with ten EFL pre-service teachers to elicit their perceptions of the study programme. Data were analyzed quantitatively and qualitatively. Findings revealed that using a program based on Instagram and social media engagement techniques was effective in developing EFL pre-service teachers' speaking skills and intercultural awareness.
