The Nagoya Municipal Subway (名古屋市営地下鉄, Nagoya Shiei Chikatetsu), also referred to as simply the Nagoya Subway,^[3] is a rapid transit system serving Nagoya, the capital of Aichi Prefecture in Japan. It consists of six lines that cover 93.3 kilometers (58.0 mi) of route and serve 87 stations.^[1] Approximately 90% of the subway's total track length is underground.

The subway system is owned and operated by the City of Nagoya Transportation Bureau and, like other large Japanese cities including Tokyo and Osaka, is heavily complemented by suburban rail, together forming an extensive network of 47 lines in and around Greater Nagoya. Of them, the subway lines represent 38% of Greater Nagoya's total rail ridership of 3 million passengers a day.^[4]

In 2002, the system introduced Hatchii as its official mascot.

The six lines that comprise the Nagoya subway network are, for the most part, independent. However, Meikō Line services partially interline with the Meijō Line, and the operations of both lines are combined. Therefore, there are in fact five distinct services on the subway. They are mostly self-contained, but two of its lines have through services onto lines owned and operated by Meitetsu, the largest private railway operator in the region. One of these, the Kamiida Line, is essentially an extension of the Meitetsu Komaki Line to which it connects.

The first two subway lines, the Higashiyama and Meijō/Meikō Lines, run on standard gauge track and use 600 volt DC electrification from a third rail. They are three of the eleven subway lines in Japan which use both third-rail electrification and standard gauge track (the Ginza and Marunouchi lines in Tokyo are the only other two lines to use third rail at that voltage; five of the eight lines of the Osaka Metro and the Blue Line in Yokohama all use 750 V DC third rail). Subsequent lines were built to narrow gauge and employ 1,500 volt DC electrification from overhead lines, in common with most other rapid transit lines in the country.

As with other railway lines in Japan, tickets can be purchased from ticket vending machines in stations. Since February 2011, this has largely been supplemented by Manaca, a rechargeable smart card. In 2012, Manaca replaced Tranpass, the predecessor integrated ticketing system, which was also able to be used at subway stations and for other connected transportation systems in the region.^[5]

On January 4, 2023, four stations were renamed:^[6]

• Nakamura Kuyakusho → Taiko-dori
• Shiyakusho (City Hall) → Nagoyajo (Nagoya Castle)
• Temma-cho → Atsuta Jingu Temma-cho
• Jingu Nishi → Atsuta Jingu Nishi
