Objective: Antisemitism is prejudice against, hostility toward, or hatred of Jews. This prejudice has negatively impacted pediatric psychology practitioners, learners, and patients, leading to increased fear and psychological harm. A group of Jewish-identifying pediatric psychologists and psychology learners assembled to outline antisemitism in the context of pediatric psychology practice, research, and training, provide a brief primer on Judaism and present actionable strategies to support Jewish colleagues, learners, and families. Method: The negative impacts of antisemitism within pediatric psychology are outlined, and a review of relevant literature invites practitioners and researchers of varying levels and disciplines of pediatric psychology to recognize and combat antisemitism. There are no human subjects; consent and institutional review board were not needed. Results: Antisemitic microaggressions and prejudice experienced and/or witnessed by authors are briefly described and synthesized, with four core themes emerging: overtly antisemitic behavior, tropes/stereotypes, erasure/invisibility, and silencing. Finally, recommendations for action using the antisemitism-adapted STYLE framework and the opportunity for inclusion of Judaism in diversity, equity, and inclusion work are provided. Conclusions: By promoting a better understanding of Judaism and the Jewish people, this article encourages increased consideration for Jewish identity and Jewish experience in pediatric psychology practice, research, and training.
