The present study investigated the effectiveness of using storytelling strategy for enhancing EFL vocabulary learning among primary stage pupils. The design of the study was the quasi-experimental, two-groups pre-posttest. The study sample consisted of (60) pupils selected from primary stage pupils in the academic year 2023-2024 at Al-Azhar Primary Institute at the first term. The instruments and materials of the study were: an EFL Vocabulary learning checklist including three main aspects and other sub-skills, an EFL Vocabulary learning pre-posttest and the storytelling strategy. The EFL vocabulary aspects pre- test was administrated to the participants of the control and the experimental groups to determine their levels of EFL vocabulary skills then the experimental group was taught using storytelling- based strategy. After that, the groups were post-tested using the EFL vocabulary aspects test. The findings of the study revealed that EFL vocabulary learning was significantly developed due to the use of a storytelling- based strategy for developing EFL vocabulary learning among primary stage pupils enrolled at Al-Azhar Primary Institute, Benha, and Qalioubya. Thus, it can be concluded that using Storytelling- based Strategy is effective in developing primary pupils' EFL vocabulary learning.
