Glen River is a short river in County Down, Northern Ireland. The two-mile (3.2 km) course flows north-east from the foot of Slieve Commedagh and Slieve Donard in the Mourne Mountains into Dundrum Bay at Newcastle, descending 1,500 feet (460 m).

It is quite a fast-flowing river with many small waterfalls and deep pools. The bedrock is composed of granite in the upper parts, becoming dark shale lower down. It flows through Donard Forest and Donard Park and is crossed by five bridges. The path that runs alongside the river is commonly used by walkers climbing Slieve Donard.
