John Grono (c. 1763–4 May 1847) was a settler, sailor, ship builder, ship captain, sealer, whaler and farmer who migrated to Australia in 1799 from Wales. Captaining the ship Governor Bligh, he would later go on to be the first European to fully explore and name parts of the southwestern coast of New Zealand's south island including Milford Sound, Bligh Sound and Elizabeth Island.
