The distribution of this species is poorly known, though it appears to be circumpolar and fairly common throughout its range (Jefferson et al. 1994, Lipsky 2002). Southern right whale dolphins are found only in cool temperate to subantarctic waters of the Southern Hemisphere, mostly between about 30°S and 65°S. The southern limit appears generally to be bounded by the Antarctic Convergence. The range extends furthest north along the west coast of continents, due to the cold counter clockwise currents of the Southern Hemisphere. The northernmost record is at 12°S, off northern Peru.
