The rusty-collared seedeater (Sporophila collaris) is a species of bird in the family Thraupidae, formerly placed in the related Emberizidae. It is found in Argentina, Bolivia, Brazil, Paraguay, and Uruguay. Its natural habitats are subtropical or tropical seasonally wet or flooded lowland grassland, swamps, and heavily degraded former forest.
The rusty-collared seedeater was included by the French polymath Georges-Louis Leclerc, Comte de Buffon in 1775 in his Histoire Naturelle des Oiseaux. The bird was also illustrated in a hand-coloured plate engraved by François-Nicolas Martinet in the Planches Enluminées D'Histoire Naturelle which was produced under the supervision of Edme-Louis Daubenton to accompany Buffon's text. Neither the plate caption nor Buffon's description included a scientific name but in 1783 the Dutch naturalist Pieter Boddaert coined the binomial name Loxia collaris in his catalogue of the Planches Enluminées. Buffon mistaken believed that his specimen had come from Angola. In 1904 the Austrian ornithologist Carl Eduard Hellmayr designated the type location as Rio de Janeiro in Brazil. The rusty-collared seedeater is now placed in the genus Sporophila that was introduced by the German ornithologist Jean Cabanis in 1844. The genus name combines the Ancient Greek sporos meaning "seed" and philos meaning "-loving". The specific collaris is Latin for "of the neck".

GBIF citizen-science records
It is estimated from how often the Rusty-collared Seedeater is recorded against all the birds logged in Parque Estadual Encontro das Águas (257 verified sightings from 2019 to 2026), calibrated against known sighting rates.
