Gallicolumba is a mid-sized genus of ground-dwelling doves (family Columbidae) which occur in rainforests on the Philippines, Indonesia, and in the Pacific region. They are not closely related to the American ground doves (genus Columbina). Rather, the present genus is closest to the monotypic thick-billed ground dove genus Trugon.

This genus includes the Pacific ground doves and the bleeding-hearts known from the Philippines. The latter are named for their vivid-red patch on the breast, which looks startlingly like a bleeding wound in some species and has reminded naturalists of a dagger stab. The diet of doves of this genus consists of fruits and seed.

Trugon and Gallicolumba might be ranked as a (very small) subfamily, but the available data suggests that they are better considered part of a quite basal radiation of Columbidae which consists of many small and often bizarre lineages (e.g. Goura and Otidiphaps which are ecologically convergent to Galliformes, and maybe even the famous didines (Raphinae). Currently not quite 20 species of Gallicolumba are extant. Of the larger genera of Columbidae, Gallicolumba is the one most affected by extinction. 3-4 species have disappeared since the 18th century, and most of the remaining are decreasing in numbers, threatened with extinction or have lost subspecies due to habitat destruction, invasive species, or overhunting. In addition, there are several species never studied alive but known from subfossil bones. These became extinct during the human settlement of the Southern Pacific region (c. 3000 BC - 1400).
