This study explores the experiences and identities of nonbinary autistic people, an under-researched population. While past studies have posited a co-occurrence of autism and transgender identity, little research focuses specifically on nonbinary autistic adults. This community-based study draws on interview data from 44 nonbinary participants. Participants expressed nuanced and informed understandings of their gender identities, highlighting fluidity and a rejection traditional binary gender roles. Participants discussed the connection of their autistic and nonbinary identities and how their identity is shaped by external forces such as politics, community, and interpersonal relationships. Findings highlight the need for the inclusion of nonbinary autistic people in autism research and for autism services and programming to be affirming of various gender identities.
