The present study aimed at investigating the effectiveness of an online program based on StoryJumper for developing EFL 2^nd year pupils' oral proficiency skills. One instrument was developed for the purpose of this study; a pre-post oral proficiency skills test. The participants of the study consisted of sixty students selected randomly from EFL 2^nd year pupils at Damietta Official Language School in the academic year 2023/2024. The study adopted the quasi-experimental research design. Therefore, the participants were randomly assigned into two groups: an experimental group (n=30) and a control one (n=30). The experimental group received training through the proposed program based on StoryJumper. On the other hand, the control group received instruction through the regular method. Participants were pre- and post-tested on the instrument: the EFL oral proficiency skills test (CRST).  Results revealed that the experimental group outperformed the control group in the post administration of the EFL oral proficiency skills test. The study concluded that the program based on StoryJumper (an online storytelling platform) enhanced EFL 2^nd year pupils' oral proficiency skills. A number of recommendations and suggestions for further studies were presented.
