Rocha River or Kunturillu River (Quechua kunturillu black and white, Hispanicized spelling Condorillo, also Kundurillu, Kunturillo) which upstream is called Mayllanku (Maylanco) is a Bolivian river in the Cochabamba Department, Quillacollo Province. From the point of the confluence with the Arque River the river is called Caine River.

The river owes its present name to Captain Martín de la Rocha who diverted the river in 1565.
