Giovanni de Riu (10 March 1925, in Macomer – 11 December 2008) was a racing driver from Italy.
He failed to qualify for the 1954 Italian Grand Prix, with a privately entered Maserati.
After racing he became a key figure in the CSAI (Commissione Sportiva Automobilistica Italiana) and was involved in the enquiry into Jochen Rindt’s fatal accident in practice for the Italian Grand Prix in Monza in 1970. Info from Wiki
