The electoral district of Ross Smith was an electorate for the South Australian Legislative Assembly. It was replaced by the electoral district of Enfield for the 2002 election. Sir Ross Macpherson Smith was a member of the Australian Light Horse at Gallipoli and Sinai during World War I. He then joined the Australian Flying Corps after learning to fly in Egypt. He and his brother won the 1919 England to Australia air race (taking almost a month) and established an aerodrome at Northfield.
