See text Geospizopsis is a genus of seed-eating birds in the tanager family Thraupidae that are commonly known as sierra finches.

A molecular phylogenetic study of the tanagers published in 2014 found that Phrygilus was polyphyletic.

[2] In the subsequent rearrangement to create monophyletic genera, the genus Geospizopsis was resurrected.

[3][4] It had originally been introduced in 1856 by the French naturalist Charles Lucien Bonaparte with Passerculus geospizopsis Bonaparte, 1853 as the type species.

[4] The genus name combines Geospiza, a genus introduced by John Gould in 1837, with the Ancient Greek opsis meaning "appearance".
