Sebatik Island (Indonesian/Malay: Pulau Sebatik) is an island off the eastern coast of Borneo, partly within Indonesia and partly within Malaysia. Sebatik Island lies between Tawau Bay (Teluk Tawau) to the north and Sibuku Bay (Teluk Sibuku) to the south. The town of Tawau lies in Sabah just to the north. The island is bisected at roughly 4° 10' north by the Indonesia–Malaysia border - the northern part belongs to Sabah, Malaysia (Sebatik Malaysia) while the southern part belongs to North Kalimantan.
