Between the 1870s and 1890s, the Italian (Royal Navy) built a series of torpedo cruisers, as part of a program intended to strengthen the fleet during a period of limited naval budgets. A total of six different classes comprising eighteen vessels were constructed. The first vessel, , was laid down in 1875, and was one of the first torpedo cruisers built by any navy. She proved to be a disappointment in service, being too slow to be an effective warship. was followed by the more successful design, , which provided the basis for the four s and the eight-vessel . The four s were built on an experimental basis, with being used as the basis for the s. While those vessels were being built, a pair of smaller vessels—the —were ordered. The final class, which comprised and , was built in the late 1890s to be fleet scouts. Like , the class was too slow for its intended role.
Most of the Italian torpedo cruisers served during the relatively uneventful 1880s, 1890s, and 1900s, and as a result, saw little activity outside of routine training operations. By the early 1900s, many of the cruisers had been reduced to subsidiary roles or had been discarded outright. A handful of vessels, specifically of the and classes, were still in front-line service by the time of the Italo-Turkish War in 1911–1912, and they saw action primarily as coastal bombardment vessels supporting Italian forces operating in North Africa. The surviving vessels still in service during World War I saw no offensive operations, though four—, , , and —that had been converted into minelayers, were employed to help blockade the Austro-Hungarian Navy in the Adriatic Sea. was torpedoed and sunk by a German U-boat in March 1918, the only Italian torpedo cruiser to be lost to hostile action. Long since obsolete by the early 1920s, the remaining torpedo cruisers were then sold for scrap. Their place in the fleet's reconnaissance force was taken by a group of German and Austro-Hungarian light cruisers that were acquired as war reparations.

In the aftermath of the Italian fleet's defeat at the Battle of Lissa in 1866, the Italian parliament drastically reduced naval budgets. By the 1870s, the small budgets precluded the acquisition of a large battle fleet centered on new ironclads like the then under construction, and so Admiral Simone Antonio Saint-Bon, then the Italian Minister of the Navy, ordered a small, fast vessel that was armed with torpedoes. The experimental vessel was to provide the basis for further such ships, which would increase the combat power of the at a fraction of the cost of a new ironclad. The new vessel was one of the first torpedo cruisers to be built by any navy. Her flat-bottomed hull prevented her from reaching her intended speed, which meant that she would be unable to catch the ironclads she was intended to destroy. She spent little time in active service as a result, and the Italian navy did not build another torpedo cruiser for almost another decade. In November 1893, the navy sold the vessel and she was subsequently broken up.

By the mid-1880s, Engineering Inspector Benedetto Brin—the designer of the and s—had begun to experiment with the ideas of the , which emphasized small, fast, torpedo-armed vessels that could damage or destroy the much larger battleships at a fraction of the cost. His first experiment was a new torpedo cruiser that was to correct the defects of , most importantly her slow speed. The new vessel, , was nearly faster than , and she carried five torpedo tubes to s single tube, significantly increasing her offensive power. She was so successful that she proved to be the basis for twelve more similar vessels of the and es built over the following decade.
served with the Italian fleet until 1910, during which time she participated in extensive fleet training exercises that helped to develop Italian naval doctrine and tactics. She was modernized in 1897–1898, receiving new boilers and a modified bow, among other changes. In 1910, she was converted into a minelayer. She served in this capacity during the Italo-Turkish War of 1911–1912 but she saw no action during the conflict. She remained in service through World War I, during which the Italian fleet made extensive use of minefields to keep the Austro-Hungarian Navy contained in the narrow waters of the Adriatic Sea. remained in the fleet's inventory until 1923, when she was discarded and broken up for scrap. By that time, she was the last Italian torpedo cruiser, having served for more than thirty-six years.

Goito class
Brin continued his experimentation with the class, adopting different hull forms, propulsion systems, and light gun batteries to determine the most effective configuration for the new warship type. He was joined in this task by Engineering Director Giacinto Pullino, who prepared the design for . Despite their variations, all were broadly similar to , upon which their designs were based. The follow-on class adopted the two-shaft engine arrangement that had been used in , along with her gun armament suite, which included a single gun; she was the only member of the class to carry a medium-caliber gun.
Like , the four s served with the fleet and participated in training exercises. These exercises frequently gamed the problem of a French naval attack on various Italian ports, France then being Italy's most likely adversary, owing to Italy's membership in the Triple Alliance with Germany and Austria-Hungary. When not conducting maneuvers, the ships were frequently placed in reserve to reduce operational costs. By the late 1890s, the ships began to be withdrawn from frontline service, with being converted into a minelayer in 1897, becoming a training ship in 1898; and were simply stricken from the register in 1901 and sold for scrap. During World War I, supported the minelaying operations against Austria-Hungary, and she and were both discarded after the war in 1920.

Folgore class
The next class of torpedo cruisers built for the Italian fleet, the class, marked further experimentation on the part of Brin. These two ships were significantly smaller than the other torpedo cruisers Brin designed, though they still carried an armament of three torpedo tubes, and they were nearly as fast as the s. They were not particularly successful vessels and their design was not repeated in future torpedo cruisers. The ships had uneventful careers, though this was in part due to the fact that was badly damaged in a collision with the protected cruiser early in her career, and she could not be repaired to her original configuration. was frequently placed in reserve, and in 1897 she became a gunnery training ship. was broken up in 1900, and was dismantled in 1908.

Partenope class
Design work on the class began in 1887, with as the basis; the -class cruisers had not yet entered service at that point, and so the navy had not gained any experience from the variations in their arrangements. Nevertheless, the design staff decided to standardize on the two-shaft arrangement adopted for , since it was a simpler and cheaper solution if it did not match the speed of the three-shaft systems. And with more powerful engines, the -class cruisers were faster than the three-shaft s, reaching speeds as high as . For their gun armament, the s also adopted the battery installed on , since the medium-caliber significantly increased her combat power. The designers conducted further tests with the ships' armaments, and received a second 4.7-inch gun.
Like the other Italian torpedo cruisers, the class spent much of its career with the fleet conducting training exercises. In the 1890s, and participated in naval demonstrations off Crete in attempts by the Great Powers to prevent conflicts between Greece and the Ottoman Empire over control of the island. By the mid-1900s, the class began to be withdrawn from front-line service. and were converted into minelayers in 1906–1908 and 1909–1910, respectively, and and were sold for scrap in 1907. Several members of the class saw action during the Italo-Turkish War, primarily shelling Ottoman positions in North Africa. briefly engaged the Ottoman torpedo cruiser in the Red Sea.
After the war, the navy discarded , , and . The three surviving members of the class, , , and , continued in service during World War I, but they saw limited activity due to the cautious strategy adopted by the Italian fleet. The two minelayers were tasked with laying defensive minefields in the Adriatic, and on 24 March 1918, the German U-boat UC-67 torpedoed and sank off Bizerte. and were both scrapped in the early 1920s.
