The park submerged Gaiola (Italian: Parco sommerso di Gaiola) is the name of a marine protected area in the Bay of Naples.

Established in 2002, the park takes its name from two homonymous islands near the coast of Posillipo. In a sea area of 42 hectares, the protected area surrounds Gaiola islands and extends from the small town of the Bay of Marechiaro to Trentaremi bay.
