Transformative justice is a vision, a framework, and a theory of change which pushes for radical abolition and reimagining of entire systems. It is a community-led strategy which centers on and seeks to uproot structural determinants of oppression. In this article, I outline how applied linguistics can and should draw on transformative justice principles as a methodology for doing applied linguistics and as an underpinning theory of change for the discipline itself. I explore how transformative justice in applied linguistics involves addressing the colonial roots of the discipline and its complicity in perpetuating raciolinguistic ideologies and co-constituted discourses of linguistic deficiency. I argue for new conceptualizations of impact which prioritize community solidarity. I argue for applied linguists to end collaborations with the police, the military, and the prison industrial complex, showing how these collaborations rely on systems of punitive accountability and modest reforms. I argue that transformative justice is a life-affirming theory of change for the discipline of applied linguistics and for the marginalized communities we work with.
