Tukangbesi Islands, is a group of islands off the coast of Sulawesi immediately east of Buton island in the Banda Sea region, and part of Sulawesi Tenggara. The main islands are Wangiwangi Island, Kaledupa Island, Tomia Island, and Binongko Island, commonly abbreviated as Wakatobi and now under one administration, Wakatobi Regency. "Tukang Besi" literally means "iron worker" or "blacksmith" in Indonesian. This archipelago is called "tukangbesi" (blacksmith) because this archipelago is famous for making the best traditional keris which are still produced today. There is a Tukang Besi language. Separating Buton and the group is the Gulf of Kolowana Watabo.
