The line-cheeked spinetail (Cranioleuca antisiensis) is an arboreal species of bird in the ovenbird family Furnariidae. It is a common species in the Andes in Ecuador and Peru. Its natural habitat is subtropical or tropical moist montane forests, woodland and scrub. It is distinguished from other species by its distribution, behaviour and white supercilium. There are two recognized subspecies, which are in reality a gradient in morphology and plumage from one extreme to the other.
The IUCN Red List conservation status is rated as Least Concern, as the line-cheeked spinetail is common along its range and is presumably stable. However, since it is arboreal, the line-cheeked spinetail is vulnerable to deforestation. Yet, it is relatively tolerant to human disturbance and does well in successional vegetation.
