The '''mountain serpent eagle''' ('''''Spilornis kinabaluensis'''''), also known as the '''Kinabalu serpent eagle''', is a bird of prey that is found in northern Borneo.<ref>{{cite book |title=Phillipps' Field Guide to the Birds of Borneo |author=Phillipps, Quentin |author2= Phillipps, Karen |name-list-style= amp |year=2011 |publisher=John Beaufoy Publishing |location=Oxford, UK |isbn=978-1-906780-56-2 }}</ref> It is found at altitudes of {{convert|1000|-|4100|m|ft}} in forest, especially where it becomes stunted. Where their range overlaps, the crested serpent eagle generally occurs at lower altitudes. The mountain serpent eagle is darker than the Bornean subspecies of the crested serpent eagle.
The mountain serpent eagle is threatened by habitat loss. However, they occur within the Kinabalu National Park and the Gunung Mulu National Park. Their high-altitude habitats are usually too remote for logging and agriculture, making some of its range secure.
