The Suzuki X-90 is a front-engine, rear or all-wheel drive, two-door, two-seater SUV manufactured and marketed by Suzuki for model years 1995-1997. Related to the Suzuki Sidekick, the only difference is the body and available options. The X-90 featured a T-section removable roof.

Replacing the Samurai in the United States market, Suzuki began marketing the X-90 in Japan by the end of 1995, and in western markets in April 1996.

The X-90 used a 1.6 L I4 16-valve engine which produced 95 hp (71 kW) and was available with four wheel drive or rear wheel drive and either a 5-speed manual or automatic transmission. The X-90 featured dual air bags, anti-lock brakes, optional air conditioning and a dealer-installed 6 disc CD changer. The suspension used MacPherson struts and coil springs in front and coil springs with wishbone and trailing links in the rear. A space saver spare wheel is stored in the trunk and space behind the two seats offers further cargo area.

The X-90 debuted as a concept car at the 1993 Tokyo Motor Show. Suzuki presented the production vehicle in 1995 and began marketing the X-90 by the end of that year in Japan, with international markets the following year. The X-90 sold 1,348 X-90s examples in Japan, and a total of 7,205 X-90s were imported into the US. More than half in the US were sold in 1996, with sales of 2,087 the next year and 477 in 1998. During 1996, 484 vehicles were imported into Australia. The X-90 was also imported into Europe. By mid-1997 retail pricing had dropped by 25%. No further imports occurred and the last of the vehicles sold in 1999.

The X-90 was the base vehicle for Red Bull's advertising vehicles, which featured a 1.5 m (5') mockup of the company's product can mounted over the trunk.

In October 2013, Top Gear Magazine placed the X-90 on its list of "The 13 worst cars of the last 20 years."
