Solanum neorossii (neorossii, in honor of German potato breeder Hans D. Ross) is a species found in northern Argentina, close to the Bolivian border.  It was first described in 1983 from materials collected in 1966 (Hawkes 1983).

Vega (1995) found that this species is more frost tolerant than domesticated potato.

This species carries a resistance gene to powdery mildew caused by Golovinomyces orontii or G. cichoracearum (Park 2009).

The chloroplast genome of this species occurs in two different haplotypes (Hosaka 2003).
