Thomas Reynolds (27 January 1818 – 25 February 1875) was the fifth Premier of South Australia, serving from 9 May 1860 to 8 October 1861. Reynolds was born in England in 1818, and on leaving school had experience in the grocery business. He came to South Australia in 1840 as an early colonist at the invitation of his brother, who had a draper's shop at Adelaide. The brother had died by the time Thomas Reynolds arrived and he soon opened a grocer's shop, was successful for a time, but like many others fell into financial difficulties when the gold rush began.
