The Timberline Sparrow ("Spizella breweri taverneri") is a taxonomically controversial American sparrow. Usually treated as a subspecies of Brewer's Sparrow, it is still considered a distinct species "Spizella taverneri" by many authorities. While the Timberline Sparrow recognizably differs in some details, there is little reproductive isolation between the taxa.

When it was still considered a good species, it was listed as Least Concern by the IUCN [E.g. Baillie "et al." (2004).] .
