The Isuzu Piazza (also known as the Isuzu Impulse in the United States and the Holden Piazza in Australia) is a small, sporty 3-door liftback coupé that was manufactured by Isuzu from 1981 to 1992 in two generations. In Australia it was sold by Holden, the local division of Isuzu's parent company, General Motors (GM).

The first generation Impulse was a rear-wheel drive car, and in the United Kingdom it was the first widely available Isuzu passenger car. The second generation was available as front-wheel drive or all-wheel drive. It was the basis for the Gemini Coupe, or Geo Storm as it was known in the US market.

As of 2010, the number of registered Impulses totaled only 2,300, making Impulses very rare. The car was produced in very low numbers, totaling slightly over 13,000 units, with that number including the production of the Isuzu Stylus. The Impulse is considered today to be one of the rarest 80's/90's era automobiles.

In 1978, Isuzu commissioned Giorgetto Giugiaro to design a new sporty car to replace the 117 Coupe (also a Giugiaro design). They delivered several T Series Chevettes (developed in 1973 in South America) to the Italdesign studio in Italy and allowed Giugiaro free rein over the design. The result of this effort was the wedge-shaped three-door hatchback called the Asso di Fiori ("Ace of Clubs") prototype and show car. It was shown at the 1979 Tokyo Motor Show to rave reviews. Giugiaro referred to the design as his fifth "Copernican revolution", integrating the design innovations of many different previous designs into one, mass producible, vehicle. Within 48 hours of its unveiling at the Tokyo Motor Show, Isuzu fast tracked the vehicle into production with minimal changes to the design. Items that remained were the single blade front windshield wiper, and an integrated steering wheel adjustment that also moved the instrument cluster, with wiper controls and exterior lighting controls installed just behind the steering wheel on either side.
