Luis Nicanor Pablo Díaz González-Viana (born June 1951 in Zamora), is a Spanish anthropologist, philologist and writer.

He participated in the research project of CSIC 'Sources of Spanish ethnography' led by Julio Caro Baroja who, along with professors of the University of Berkeley like Stanley Brandes and the folklorist Alan Dundes, Luis Díaz considers one of his teachers.

He has been part of the research teams of projects like 'The Archive of Mourning' – about the popular expressions that took place after the attacks of 11 March 2004 – or like 'Justice, Memory, Narration and culture'.

Since 2012 he co-directs at the University of Valladolid, with Dámaso J. Vicente Blanco, the 'European Training Course in Management of Intangible Cultural Heritage' and directs the team of researchers who carry out the ethnographic pre-inventories of several provinces of Castile and León.

The anthropologist Díaz Viana denounces the current acculturation when it is accepted without criticism by the overmodernity – technological fetishism and logic of economic progress – that inevitably distances us from the human reality.

He also criticizes some proposals to protect the rural environment: a conservationist model of nature, landscapes and countryside that has left the people who still live in it as figurines dams on postcards that some administrations keep there only to be visited.
