This article introduces central features of transnational feminism and discusses how these characteristics provide a foundation for transnational feminist practice in psychology. These core themes emphasize: (a) reflexivity and positionality; (b) intersectionality in transnational perspective; (c) inclusive definitions of global and transnational feminisms; (d) transnational border-crossing practices; (e) agency and resistance in global perspective; (f) decolonization of theory, knowledge, and practice; (g) egalitarian collaboration and alliance building; and (h) theories and practices that support critical consciousness and social change. Examples of how these features are highlighted by this special issue's authors are integrated with summaries of themes.
