The Mountain Grackle (Macroagelaius subalaris) is a species of bird in the Icteridae family. It is endemic to Colombia.

Its natural habitat is subtropical or tropical moist montane forests. It is threatened by habitat loss and declining in numbers. It was uplisted from Near Threatened to Critically Endangered status in 2000, due to fears of a collapse of the presumably tiny population. As the species, while still severely declining, has turned out to be more widespread than believed, it is downlisted to Endangered in the 2007 IUCN Red List.
