In this article, we conceptualize youth-led antiracism research in developmental science. First, we discuss how Youth Participatory Action Research (YPAR) principles converge with critical race epistemological approaches to knowledge production. Second, we propose that youth-led antiracism research requires a commitment to multiple ways of knowing, countering paternalism, focusing on structural racism, and activist scholarship that advances racial equity. These commitments are necessary to challenge how White supremacy culture shapes social science research paradigms. We weave existing empirical evidence and theory on YPAR with counter-storytelling methodology to identify various participatory methods and creative strategies that exemplify these commitments and emerged from co-creating research projects with ethnically and racially diverse youth. We conclude with implications for developmental science and offer guiding questions that may help scholars reimagine research in partnership with youth in ways that advance racial justice.
