Thomas Playford (11 August 1795 – 18 September 1873) was a non-conformist minister of religion, teacher and farmer in the early days of the British colony of South Australia. The first-born son of the next three generations were also named Thomas; the second and fourth became premiers of South Australia. His time in South Australia was closely linked with that of his brother, John Playford (born 1810), sister Hannah Welbourn née Playford (1813–1865), and Hannah's husband Thomas Welbourn (1812–1879).
The brothers were ordained ministers, followers of Robert Aitken, with heretical views on the nature of eternal punishment that attracted charges of Socinianism.[1][2]
