The crimson-collared grosbeak (Periporphyrus celaeno) is a medium-size seed- and leaf-eating bird in the same family as the northern cardinal, Cardinalidae.

The crimson-collared grosbeak is primarily found in north-eastern Mexico from central Nuevo León and central Tamaulipas south to northern Veracruz; however, it occasionally strays into the Rio Grande Valley of southern Texas, mostly in winter.

Mature females have a black head and breast like males but greenish upperparts and yellowish underparts.

The beak is black, big and stubby, with the upper mandible jutting roughly perpendicular to the forehead.

The crimson-collared grosbeak inhabits humid or semi-arid forest and second growth, from low to high levels, sometimes skulking on the ground.
