The Amaryllis family or Amaryllidaceae are a family of herbaceous, perennials and bulbous flowering plants included in the monocot order Asparagales, taking its name from the genus Amaryllis. The family consists of about sixty genera, with over eight hundred species with a worldwide distribution.

All members of this family, which may be described as 'amaryllids', can be recognised by their rather fleshy and two-ranked leaves and their large and showy flowers, with an inferior ovary and six stamens, arranged in umbels at the apex of leafless flowering stems, or scapes. The somewhat similar-looking members of the onion family (Alliaceae) differ in having a superior ovary and the presence of allyl sulfide compounds which give them their characteristic smell. From another close relative, the agapanthus family (Agapanthaceae), differs also in the position of the ovary and in lacking steroidal saponins.
