The Routledge Companion to Gender, Sexuality and South Korea offers a comprehensive interdisciplinary exploration of how gender and sexuality have shaped South Korean society in historical and contemporary contexts. Bringing together internationally renowned scholars from diverse fields, including sociology, politics, media and cultural studies, literature and history, the volume combines theoretical perspectives with empirically grounded case studies to examine gendered and sexual identities across intersecting social, cultural, economic and political processes. Challenging linear narratives of social progress, it highlights the continuing force of heteronormative structures rooted in Confucian legacies and family practices, while also tracing uneven and contested transformations linked to globalization, digitalization and creative cultures. By foregrounding South Korea as a dynamic non-Western case, this collection advances debates on de‑Westernization and comparative scholarship. The Routledge Companion to Gender, Sexuality and South Korea is ideal for students and scholars of gender and sexuality studies, Korean studies, sociology, media and cultural studies, anthropology, politics, history and globalization.
