Franklin Sound is a narrow waterway between the two largest islands, Flinders Island and Cape Barren Island in the Furneaux Group, at the southeastern end of Bass Strait, between Victoria and Tasmania, Australia.
Named after British explorer and Lieutenant-Governor of Van Diemen's Land (1836–1843), Sir John Franklin (1786–1847).
Numerous sandbanks and small islands obstruct the sound and the tidal stream runs at 2 to 3 knots.
FRANKLIN SOUND was named by Captain Stokes after Sir John Franklin, a distinguished naval officer and explorer, who became Lieutenant-Governor of Tasmania in 1837.
