Voltri is a quartiere of the Italian city of Genoa, located 17 kilometres (10.6 mi) west of the city centre. It was formerly an independent comune.

In 2015, Voltri and the nearby hamlets included in Genoa's VII Municipio (Crevari, Acquasanta, Vesima, Fabbriche) had a total population of 12,402. Voltri is one of the 3 former municipalities (the other ones are Pra' and Pegli) being part of the Genoa's city VII Municipio.

The area of Voltri was inhabited since prehistoric times, and was a center of the Ligures tribe of the Veituri, from which it probably took its name. In the Middle Ages it was a hamlet part of the Republic of Genoa, its main activity being the production of paper.

In 1796 Voltri was the site of a battle between the French troops of Napoléon Bonaparte and of the Austrian Empire allied with the Kingdom of Sardinia-Piedmont. After the fall of the First French Empire, it became an autonomous commune in the Sardinian territories, a status it kept until 1926, when the Fascist government united it to Genoa.
