Linaria cannabina, commonly known as the common linnet, is native to Europe, western Asia, and North Africa. It is widespread across these regions, though its presence can vary depending on the availability of suitable habitats.

The common linnet typically inhabits open and semi-open habitats, including farmland, heathland, scrub areas, and gardens. It prefers lowland regions but can also be found in upland areas up to 2,000 meters. The species favors environments with dense vegetation and abundant seeding plants, which are crucial for their diet.

Linaria cannabina is mainly a granivore, feeding on seeds from a wide variety of wild plants, though it may also consume insects, especially during the breeding season. Its ecological niche involves adapting to environments where it can exploit its primary food resources throughout the year. Variations in habitat can occur, as some subspecies might adapt to specific regional conditions, but generally, the common linnet is adaptable to a range of open habitats that provide sufficient food supply.
