Nesoryzomys indefessus, also known as the Santa Cruz nesoryzomys or Indefatigable Galápagos mouse, is a rodent of the genus Nesoryzomys of family Cricetidae from Galápagos Islands of Ecuador. It contains two subspecies: one (N. i. indefessus) formerly lived on Santa Cruz Island, but is now extinct, probably due to the introduction of black rats; and another (N. i. narboroughi) that is still alive on Fernandina Island. The two are sometimes considered to be different species.

Its specific name is Latin for "unwearied, indefatigable", but the species was named after its island, which was formerly known as "Indefatigable Island" after a ship with the same name.
