The Quartetto Italiano (English: Italian Quartet) was a string quartet founded in Reggio Emilia in 1945. They made their debut in 1945 in Carpi when all four players were still in their early 20's. They were originally named Nuovo Quartetto Italiano before dropping the "Nuovo" tag in 1951. They are particularly noted for their recording of the complete cycle of Beethoven string quartets, made between 1967 and 1975. The quartet disbanded in 1980.
The secretary and historian of the Quartet was Guido Alberto Borciani (Reggio Emilia, 20 October 1920 – 4 April 2008), mechanical engineer and talented pianist, Paolo's brother and founder in 1987 of the Premio Paolo Borciani.
