The Ascarididae are a family of the large intestinal roundworms. Members of the family are intestinal parasites, infecting all classes of vertebrates.^[1]^[2] It includes a number of genera,^[3] the most well known of which are:

Ascaris lumbricoides is the main ascarid parasite of humans, causing ascariasis.
