The Iso Fidia was a full-size four-door luxury saloon produced by the Italian manufacturer Iso Rivolta during the late 1960s and into the 1970s. Like other Iso models of the period, it combined an Italian-bodied body with American V8 power, positioning it as a grand touring saloon aimed at buyers seeking space and performance in equal measure. Production numbers were very limited, reflecting the niche nature of Iso's lineup and the broader difficulties the company faced before ceasing operations in 1974.
