Subcompact crossover SUV is an automobile segment used to describe the smallest segment of crossover SUV, a type of sport utility vehicle, below the compact crossover SUV. Subcompact crossover SUVs are usually based on a platform of a subcompact passenger car, although some high-end subcompact crossover models are based on a compact car (C-segment). The segment started to gain traction during early to mid-2010s when the number of models and sales figures rapidly increased in major markets such as North America and Europe. In 2019, around 22 percent of SUV global sales were contributed by subcompact crossovers.

A sport utility vehicle (SUV) is a car classification that combines elements of road-going passenger cars with features from off-road vehicles, such as raised ground clearance and four-wheel drive.
