Rebuilding society in the wake of conflict often falls on the generation born in peace. Yet, youth contributions to peacebuilding are often overlooked. This article challenges the narrative that sidelines the constructive contributions of young people in conflict‐affected settings. Instead, we identify different kinds of youth peacebuilders. Using a person‐centered approach, we conduct a latent class analysis of 590 adolescents (Mage = 16.8, SDage = 2.0, years old), evenly split by sex (51% female) and representing both communities, or conflict‐related identity groups, in Northern Ireland (38% Catholic, 62% Protestant). Across 10 indicators capturing different types and targets of prosocial action, the best fit to the data was a four‐class model: Peace in Name Only (36%), Peace at Home (33%), Peace Within Community (13%), and Future Peacebuilder (16%). Class membership varied based on youth's prior exposure to intergroup threat, or sectarian antisocial behavior. Prior exposure was related to a higher probability of being in the Peace at Home or Future Peacebuilder, compared to the Peace in Name Only class. The importance of recognizing the different kinds of youth peacebuilders in a conflict‐affected society is discussed, along with implications for global policy.
