The Fuga (codename Y50) is a full-size luxury car from Nissan of Japan, introduced in October 2004. First shown as the Fuga Concept at the 2003 Tokyo Motor Show, it is a direct replacement for the long running Cedric and Gloria series of cars. The Fuga is a rear wheel drive sedan riding on a stretched version of the Nissan FM platform, and uses either a 2.5 L or 3.5 L VQ-series V6 engine.

It is offered in either "XV" or "GT" trim packages, equivalent to the previous "Brougham" and "Gran Turismo" versions of the Cedric and Gloria. The 3.5 L cars are also available with all wheel drive, and top models can be specified with intelligent cruise control and four wheel steering. In the United States, the Fuga can be fitted with a 4.5 L VK-series V8 and known as the Infiniti M45, with the V6 version as the Infiniti M35
