John Andrew La Nauze (9 June 1911 – 20 August 1990) was an Australian historian from Western Australia.
Shortly after his fourth birthday, his Mauritian-born father Captain Charles La Nauze was killed by Turkish artillery fire at Silt Spur (southern ANZAC sector) Gallipoli.
He completed degrees in Arts at the University of Western Australia and (as Rhodes Scholar for 1931) at Balliol College, Oxford before joining the Economics Departments at Adelaide (from 1935) and Sydney (1940-49).
In 1950 La Nauze became Foundation Professor of Economic History in the University of Melbourne, moving to the newly created Ernest Scott Chair in the Department of History in 1956.
In 1966 he succeeded Sir Keith Hancock as Professor of History in the Institute of Advanced Studies at the Australian National University.
