The Markham River is a river in eastern Papua New Guinea. It originates in the Finisterre Range and flows for 180 km (110 mi) to empty into the Huon Gulf at Lae.

The river was named in 1873 by Captain John Moresby, R.N., in honour of Sir Clements Markham, then Secretary of the Royal Geographical Society.[3] A single-lane steel bridge, 1690 feet long – by far the longest bridge built in Papua until that time – was opened in January 1955.[4]
