Slowworms (also called blindworms and hazelworms) are a small genus (Anguis) of snake like legless lizards in the family Anguidae. The genus has several living species, including the common slowworm (A. fragilis), the eastern slowworm (A. colchica), the Greek slowworm (A. graeca), the Peloponnese slowworm (A. cephalonnica), and the Italian slowworm (A. veronensis). There are also known fossil species.

Slowworms are typically grey brown, with the females having a coppery sheen and two lateral black stripes, and the males displaying electric blue spots, particularly in the breeding season. They give birth to live young, which are about long at birth and generally have golden stripes. Slowworms are slow moving and can be easily caught, which has given rise to the folk etymology that the "slow" in slowworm is the same as the English adjective slow; the actual origin is a proto Germanic root which simply means "slowworm" (cf. German Schleiche). Principal predators are birds, badgers, hedgehogs, foxes and domestic cats. The average British slowworm can grow to 45 cm when fully mature and weigh about 100 g, females being slightly larger than the males. The tail makes up around half its length, but is indistinguishable from the body. It has been recorded to live for up to 30 years in wild, and the record age for a slowworm in captivity is 54 years (Copenhagen Zoo). The specific name fragilis (fragile) comes from the tendency of this species to shed its own tail, when threatened by predators, or if handled too roughly (caudal autotomy).

Although slowworms much resemble snakes, and are often mistaken for such, they are actually lizards that have lost their limbs completely with evolution. Slowworms can be distinguished from snakes by several features: their eyelids, which snakes lack (having brille instead); their small ear openings, which again snakes lack; and their tongues, which are notched in the centre rather than completely forked like a snake's. Further, snakes have an opening in their upper jaw to allow their tongue through, which slowworms lack.

Slowworms live in any habitat that is warm and protected, such as woodland, grassland, and heathland; they are frequently found in garden compost heaps, sometimes on purpose for pest control. Snails are usually avoided, except when they are still very young and the shell can be broken easily.

Slowworms are protected in the United Kingdom and Poland.
