The orange-breasted bunting (Passerina leclancherii) is a species of passerine bird in the family Cardinalidae.

With its wide range and large total population, the International Union for Conservation of Nature considers it as being of "least concern".

The lores, eye-ring and underparts are canary yellow, deepening to golden-orange on the breast.

The diet of this species has not been studied, but in general, buntings in this genus are seed-eaters, with some fruit and invertebrates being eaten.

The nest is a cup-shaped structure formed of rootlets, grasses and dry leaves, with a softer lining and is built in a low bush or thick scrub.
