"You Don't Have to Say You Love Me" is a 1966 song recorded by English singer Dusty Springfield, based on "Io che non vivo (senza te)" ("I, who can't live (without you)"), an Italian song with music by Pino Donaggio and lyrics by Vito Pallavicini, which was very successful in Italy.
The Italian song was introduced at the 15th edition of the Sanremo Festival by Donaggio and his team partner Jody Miller. It reached the final at Sanremo and, as recorded by Donaggio, reached No. 1 in Italy in March 1965, remaining there for three weeks. "Io che non vivo (senza te)" was prominently featured on the soundtrack of the Luchino Visconti film Sandra, starring Claudia Cardinale, which was awarded the Golden Lion at the Venice Film Festival that September.
