From a decolonizing standpoint, as proposed by Cruz and Sonn (2011), the current community psychology competencies seem insufficient because these often leave power structures intact. Consequently, we propose a decolonizing, decolonial and anti-colonial competency in community psychology practice to facilitate the practitioner’s process toward decoloniality, specifically decolonizing language, discourses, relationships and research processes with communities. A decolonial competency in community psychology practice is characterized by an iterative process of critical ethical reflexivity that aims to de-link community psychology practice from hegemonic Western Eurocentric perspectives in order to foster and center community voice, knowledge and power. Through an autoethnographic methodology we offer reflexive vignettes to illustrate a decolonial competency, and the lessons we have learned throughout community psychology practice. As a core community psychology competency, decoloniality can equip practitioners with the skills to engage meaningfully in a critical ethical reflexive practice that aligns with the discipline’s values and foundational principles.
