Line 1 (Italian: Linea 1; Italian pronunciation: [ˈliːneːa ˈuːno]) is a Naples Metro line that runs from Piscinola Scampia in suburban north-west Naples to Centro Direzionale in southeast Naples. Printed in yellow on the map, it serves 20 stations, 17 of which are underground, over 20.7 kilometres (12.9 mi).^[2] It is operated by ANM. The line has been renamed Metrò dell'Arte (Metro of Art) reflecting the presence of contemporary art works installed in some of its stations.

The line is in the process of being upgraded and expanded. When the upgrading works are completed, Line 1 will connect 27 stations and form a loop, and bring easier access to the city centre for residents of Chiaiano, Piscinola, and Scampia.

The operational route has a declared average frequency of one service every 7 minutes (from 6 AM to 9 PM), occasionally enhanced during peak weekday hours to every 6 minutes, while during other time slots (from 9 PM to end of service) it operates every 11 minutes.^[3]

The line spans 20.7 kilometres (12.9 mi) with 20 stations,^[4] covering a travel time of almost 40 minutes. Due to the complex terrain of Naples, the line features significant gradients. The route itself is intricate: there is a section where the metro negotiates a very tight and steep curve, and another where it passes through the same point as before but at a greater depth. Much of the journey is underground, except for the Colli Aminei-Piscinola-Scampia section, which runs on viaducts with elevated stations. Known as the "hillside metro" (metro collinare), Line 1 serves various hilly areas of the city, including Vomero, Colli Aminei, and the hospital district (Zona ospedaliera)

As of March 2025^[update], construction is underway for the segments from Centro Direzionale to Capodichino and from Piscinola Scampia to Di Vittorio, completing the loop.

It intersects with Line 2 at Museo - Piazza Cavour and Garibaldi stations, with Metro Line 6 at Municipio Porto station and with Metro Line 11 at Piscinola Scampia station.

In 2009, its art-themed stations earned Line 1 the Most Innovative Approach to Station Development Award in London, triumphing over three hundred competitors.^[5]
