The Maserati V8RI was a model of racing car produced by Italian manufacturer Maserati of Modena from 1936 to 1936, with a total of four units.

A Roots type supercharger and dual choke Weber carburetor, single camshaft resulted in 320 bhp (239 kW) and a maximum speed of 270 km/h (168 mph).

The "RI" denoted Ruote indipendenti, the then innovative independent four-wheel suspension.

Chassis #4501 debuted at Grand Prix de la Marne 1935, driven by Philippe Étancelin.

All four V8RIs built competed in the 1937 Vanderbilt Cup at New York's Roosevelt Field, and all four remained in the United States for many years afterwards.
