The juvenile ossifying fibroma, differentiated from the large group of ossifying fibroma based on the patient’s age, common sites, and clinical characteristics, is a rare but locally aggressive benign tumor with high recurrence rate. Herein, we report a case of juvenile ossifying fibroma located in the right mandible, which is an uncommon site. A 8-years- old male child presented to the pediatric unit of our institution with swelling on the right mandible. Radiographically, it was presented as an expanded and radiolucent lesion. Histology revelaed hypercellular fibroblastic proliferation with anastomosing osteoid trabeculae with rounded, strongly basophilic calcified mass rimmed by osteoblasts. Surgical management was done, and regular follow-up is advised
