Galleria Umberto I is a public shopping gallery in Naples, southern Italy. It is located directly across from the San Carlo opera house. It was built between 1887–1891, and was the cornerstone in the decades-long rebuilding of Naples — called the risanamento (lit. "making healthy again") — that lasted until World War I. It was designed by Emanuele Rocco, who employed modern architectural elements reminiscent of the Galleria Vittorio Emanuele II in Milan.
