Obock (also Obok, Ubuk) is a small port town in Djibouti. It is located on the northern shore of the Gulf of Tadjoura, where it opens out into the Gulf of Aden. The town is home to an airstrip and has ferries to Djibouti City, while mangroves lie nearby. The French form Obock derives from Arabic "Oboh", deformation of Oboki, a name given to the Wadi Dar'i in its middle part, upstream of its coastal delta.
