The Infiniti M is a line of mid-size luxury (executive) cars from the Infiniti luxury division of Nissan.

The first iteration was the M30 Coupe/Convertible, which were rebadged JDM Nissan Leopard.

After a long hiatus, the M nameplate was used for Infiniti's mid-luxury sedans (executive cars). First was the short-lived M45 sedan, a rebadged version of the Japanese-spec Nissan Gloria. The next generations, the M35/45 and M37/56/35h/30d, became the flagship of the Infiniti brand and are based on the JDM Nissan Fuga.

The Infiniti M30 (chassis code F31) was a 2-door GT coupe introduced with the Q45 as the start of the Infiniti line in 1989, as a stopgap until other models could be produced. The M30 was basically a Japanese Nissan Leopard built with left-hand drive and rebadged as an Infiniti, and had added luxury features. The other main changes were in the engine, transmission and suspension. The M30 was only sold in the United States.

The M30 had no factory options, but dealers offered the addition of a cellular phone and a CD player/changer. The sole engine was Nissan's VG30E, a 3.0 L SOHC V6 that produced 162 hp (121 kW) and 180 lb·ft (244 N·m) of torque, also used by many previous Nissan models such as the Maxima and 300ZX. Like the 300ZX, the M30 was a front-engined and rear-wheel drive vehicle. The transmission was Nissan's RE4R01A four-speed automatic with overdrive, as enabled or disabled by a button on the shifter. There was no option of a manual transmission. The differential was a Nissan R200-type open differential. It is generally regarded among M30 enthusiasts that the change of powertrain, weak suspension and the lack of options in these categories was a mistake on Infiniti's part, and perhaps to blame for the lackluster sales. The M30 (coupe) weighed about 3300 lbs (1498 kg), and produced 162 hp (121 kW). The M30 convertible weighed approximately 200 lbs. more, due to body and chassis reinforcements.
