Which Italian archipelago includes Capri, Ischia, and Procida?

The Campanian Archipelago includes Capri, Ischia, and Procida.

This Italian island group lies in the Tyrrhenian Sea, in and around the Gulf of Naples, and is also called the Neapolitan Archipelago. Its five principal islands are Capri, Ischia, Nisida, Procida, and Vivara. Most are administered within Italy’s Metropolitan City of Naples, although nearby minor islets can fall under other local jurisdictions.

A common mix-up involves the Phlegraean Islands. That geologically defined group includes Ischia, Procida, Vivara, and Nisida, but usually excludes Capri because Capri belongs to a different geological formation. The broader geographical term “Campanian Archipelago” is therefore the better fit when all three islands named in the question appear together.

The group has deep historical associations with Greek and Roman Naples. Its ancient name, the Parthenopaean Islands, was linked to Parthenope, an early name for Naples. Volcanism remains central to the region’s identity: Ischia and the other Phlegraean islands form part of the wider Campanian volcanic setting, while Capri is famous for its limestone cliffs and sea stacks.
