John Davies (10 June 1814 – 11 June 1872) co-founded the Australian newspaper The Mercury.
Davies was a Jew born in London, England. He was transported to Hobart, Australia as a convict in August 1831, for ordering candles on someone else's account. His father had been transported to New South Wales only a few years before.
In 1871 Davies passed the management of The Mercury to his sons, and in June, 1872 Davies opened up the theatre building (which he then owned) to homeless people seeking temporary shelter due to floods. He caught a chill from which he died on 11 June 1872.
