The sharp-beaked ground finch (Geospiza difficilis) is a species of bird in the Darwin's finch group of the tanager family Thraupidae.

It is classified as a least-concern species by the International Union for Conservation of Nature and it is native to the Galápagos Islands in Ecuador.

[3] This relatively small, slender-billed finch is endemic to the Galápagos Islands, where it is found on Fernandina, Santiago, Pinta, Genovesa, Darwin, and Wolf Islands.

[2] On the first three islands, it breeds in the humid highlands and disperses afterwards, but on the remaining smaller and lower islands the sharp-beaked ground finch is found in the arid zone year-round.

The International Ornithologists' Union have split them, while other taxonomic authorities still consider them conspecific.
