Sir John Greig Dunbar, DL, JP (19 September 1906 – 4 January 1978) was a Scottish businessman and Conservative politician who served as Lord Provost of Edinburgh from 1960 to 1963.
The lemonade company his father owned had relocated from Maryfield/East Norton Place to Albion Road around 1900.
The firm made fruit squashes (including a drink from the kola nut), ginger beer and sodas.
He was elected Lord Provost of Edinburgh in 1960 in succession to Ian Anderson Johnson-Gilbert.
His time as Lord Provost was dominated by major planning decisions (typical of all cities at that time), including the decision to clear St James Square to create the St. James Centre and promotion of the Princes Street Plan which resulted in the loss of many important historic buildings.
