Edward John Craigie (5 September 1871 – 17 January 1966) was a Single Tax League member for the South Australian House of Assembly seat of Flinders from 1930 to 1941. Born and raised in Moonta, South Australia, the son of Scottish parents, Craigie left school aged 11, initially working as an office boy before stints as a baker and butcher in Adelaide. From an early age, Craigie believed there needed to be a drastic overhaul of society to benefit the less privileged. Initially attracted to socialism, Craigie was converted to the ideas of Henry George who argued that all taxes should be abolished except for a single tax on unimproved land values (Craigie referred to it as a tax on "the rental value of land brought into existence by the collective presence of the people.")
