Vomero (pronounced [ˈvɔːmero]) is a bustling hilltop district of metropolitan Naples, Italy — comprising approximately two square kilometres (0.77 sq mi) and a population of 48,000.

Vomero is noted for its central square, Piazza Vanvitelli; the ancient Petraio, its earliest path up and down to the original city of Naples; its ancient district of Rione Antignano; Floridiana Park and Villa Floridiana; the medieval fortress, Castel Sant'Elmo; three funiculars connecting to downtown historic districts; its active pedestrian zone, aka ZTL — and its prominent location overlooking greater Naples, Mount Vesuvius, the Bay of Naples and the Tyrrhenian Sea.

Adjacent to the Arenella, Soccavo, Fuorigrotta, Chiaia, Montecalvario and Avvocata districts, the street and placenames within Vomero are typically named after noted artists, painters, sculptors, musicians, composers or architects, each with a prominent Neopolitan connection at the time of Vomero's development.

Residents go by the demonym, Vomeresi.
