Rina Ketty (1 March 1911 – 23 December 1996), whose real name was Cesarina Picchetto, was an Italian singer. She is best known for singing the legendary song "J'attendrai," which became a huge hit during World War II and was appreciated by Allied soldiers and Axis soldiers alike (equalled only by Lale Andersen's "Lili Marleen" and perhaps by Vera Lynn's "We'll Meet Again").
