Rock Davis (1833-1904) was a shipbuilder, mainly associated with his shipyard, the Rock Davis shipyard, colloquially known as 'the Big Shed', on Brisbane Water at Blackwall, New South Wales, Australia. After his death, the business of ship building was carried on by his second son, also Rock Davis. The shipyard constructed around 165 wooden-hulled vessels, between 1862 and 1913.
