The Junin canastero (Asthenes virgata) is a species of bird in the Furnariinae subfamily of the ovenbird family Furnariidae.

Genetic data show the three to be separate but closely related sister species.

[5] The Junin canastero is about 17.5 to 18 cm (6.9 to 7.1 in) long; one speciment weighed 22 g (0.78 oz).

Their iris is dark brown, their maxilla horn, their mandible grayish pink, and their legs and feet olive.

[6] The Junin canastero has a disjunct distribution in central and southern Peru.

[6][7] The Junin canastero primarily inhabits humid landscapes with tall bunch grass, sometimes those with scattered bushes and near stands of polylepis.

The Junin canastero's song is "a dry, accelerating, descending trill sometimes with a stuttering quality: tzree-tzree-tzree'ti'ti'ti'ti-ti'ti'ti-ti'ti'ti-ti'ti'tu".
