Brand authenticity has emerged as a critical determinant of consumer trust, emotional attachment, and long-term brand equity in international markets. As brands expand globally, they face the challenge of remaining “authentic” while adapting to diverse cultural, social, and institutional environments. This paper provides a comprehensive conceptual examination of brand authenticity in international markets, integrating insights from authenticity theory, signaling theory, and relationship marketing. We propose a multidimensional framework explaining how authenticity perceptions are formed across countries and how they influence brand trust, loyalty, and advocacy. The paper also outlines a methodological blueprint for cross-national empirical research and discusses managerial and policy implications for global brand strategy. By synthesizing existing literature and offering future research directions, this study contributes to international marketing scholarship and practice.
