Renato Zannetovich (28 July 1921 – 29 October 2021) was an Italian violinist and teacher.

While still a student of Umberto Nigri in 1933, he founded the Trieste Trio together with cellist Libero Lana and pianist Dario de Rosa.

He also held several courses and masterclasses in Italy and abroad: at the Music School of Fiesole (from 1981 to 2003), at the Accademia Musicale Chigiana in Siena and at the Superior School of Chamber Music of the Trieste Trio in Duino (at the Collegio of the United World of the Adriatic).

In 2007 Zanettovich was the recipient of a "President of the Republic Award" of the National Academy of Santa Cecilia in Italy.

The prize was presented by the then President of the Italian Republic, Giorgio Napolitano.
