The Kiunga-Tabubil Highway is an all-weather gravel road that runs from the river port town of Kiunga through Ningerum and Tabubil to the Ok Tedi Mine site, in the remote North Fly District of the Western Province of Papua New Guinea.

It is maintained by Ok Tedi Mining Limited, who are the greatest beneficiaries of the road.

In 2019 it was announced that the highway would be sealed over three years by OTML under the government tax credit scheme at an estimated cost of K100 million.

The full length of the road was first cycled in 2013 by Luke Jackson, Dylan Carroll, Michael Hayen and Mikel Wolters.
