Otherkin Wiki is an independent knowledge resource about otherkin and the wider alterhuman community. It explores a subculture whose members may understand themselves as something other than human, alongside related identities, experiences, histories, and communities. The wiki aims to balance reliable research grounded in quality sources with respect for the diversity and personal nature of these experiences.

Its articles cover identity labels such as otherkin, therianthrope, otherhearted, fictionkin, and plurality, as well as species identities including wolf, elf, cat, fae, dragon, and deity. Visitors can browse articles by category, discover recent changes, or use the random article feature. The site also provides guidance for contributors, including editing help, policies, sourcing advice, and an article workshop.

Otherkin Wiki supports community participation through its discussion spaces, town hall, and Stoat server, and shares updates through social media. It is a member of the Independent Wiki Federation, which helps independent wikis exchange support, expertise, and resources.
