Metronapoli SpA was an Italian company responsible for the provision of public transport in the city of Naples, and its primary function was the operation and maintenance of the Naples Metro system.

Its functions were absorbed by Azienda Napoletana Mobilità s.p.a. (ANM) on 1 November 2013.

[1] Metronapoli was a subsidiary company controlled by two organisations, initially three.

From 2001 to 2005, the Comune di Napoli (City of Naples government) had a 51% holding stake in the company shares, giving them a controlling ownership, while Trenitalia held a 38% stake and ANM held the remaining 11%.

[2][3] Trenitalia sold its shares to the municipal government in November 2005, and at the end of 2005 the latter's stake had grown to 99%, with just 1% owned by ANM.
