Ruschi's rat or Ruschi's spiny mouse (Abrawayaomys ruschii) is a rodent species found in Argentina and Brazil. Some cranial features suggest it may be an archaic relative of the paramo Oldfield mouse (Thomasomys paramorum). The upper parts are greyish yellow with a darker head and yellowish-white underparts. Fine hairs are mixed with flattened and grooved spines that are most numerous on the back.
