The Festivus was a monthly peer-reviewed scientific journal about malacology and conchology published by the San Diego Shell Club. It was established in 1970 as a shell club newsletter, gradually evolving into a scientific journal. Its name, The Festivus, is in honor of a species of sea snail that occurs locally: the "festive murex", previously known as Murex festivus, and now known as Pteropurpura festiva.
In February 2014, it was announced that The Festivus would, from that point on, be published quarterly, and would no longer be a peer-reviewed journal.
Occasionally, The Festivus published book-like "Special Supplements". Some examples are:
- Superfamily, Muricacea: Catalogue of Coralliophilidae by Antony D'Attilio
- The recent molluscan marine fauna of Isla de Malpelo, Colombia by Kiestie L. Kaiser
- An atlas of Cowrie Radulae (Mollusca: Gastropoda: Cypraeoidea: Cypraeidae) by Hugh Bradner and E. Alison Kay
