The yellow-breasted brush finch (Atlapetes latinuchus), also known as the cloud-forest brush finch, is a species of bird in the family Emberizidae. It is sometimes considered a subspecies of Atlapetes rufinucha. It is found in forest and woodland in the Andean highlands of northern Peru, through Ecuador and Colombia, to far western Venezuela. It is generally common, and therefore considered to be of least concern by BirdLife International. A new subspecies, A. l. yariguierum, was described in 2006 from Serranía de los Yariguíes in Colombia.
