The olive finch (Arremon castaneiceps) is a species of bird in the family Passerellidae. Until recently, it was placed in the genus Lysurus.
It is found in the Andes of Colombia, Ecuador and far northern Peru where its natural habitat is subtropical or tropical moist montane forest. The olive finch is listed as Near Threatened by the IUCN Red List. The olive finch is related to the sooty-faced finch and ornithologist Carl Eduard Hallmayr even suggested they should be classified as the same species.
