The grey-breasted seedsnipe (Thinocorus orbignyianus) is a species of bird in the family Thinocoridae.

The male has a gray head, neck, and upper breast, and a white throat with a black border.

T. o. ingae is found from the Department of Cajamarca in Peru through western Bolivia into northern Chile and northwestern Argentina as far as Catamarca and possibly Mendoza Provinces.

The nominate subspecies is found from northern Chile's Antofagasta Region and northwestern Argentina's La Rioja Province south into Tierra del Fuego.

It is a year round resident in most of its range though it moves north out of Tierra del Fuego in winter.

[4] The grey-breasted seedsnipe inhabits Puna grassland, mostly in areas with low matted vegetation or short grass near bogs.
