Jaco Island, sometimes spelt Jako, is an uninhabited island in East Timor and lies within Nino Konis Santana National Park. Jaco situates just off the eastern end of the island of Timor, part of the Tutuala subdistrict in Lautém District, and is separated from the mainland in front of Valu Beach by a 700 m wide channel navigable by small vessels. The white sands and untouched marine life attract many people to this remote location.
