Despite the ever-growing consumer demand for authenticity, especially in the context of the experience economy, authenticity is still contested in terms of conceptualisation and application. This paper proposes a framework which conceptualises authenticity in co-created experiences and explores the interactions of three fundamental elements of experience co-creation. The framework also suggests important insights that emerge from such interactions. By proposing the framework, this paper points out the significance of stimulating the interactions to enhance consumer's' perceived authenticity especially in co-created experiences, of which values have been increasingly recognised. The proposed framework therefore is not only applicable for conceptualising authenticity in tourism and hospitality, but also deemed useful for stimulating consumer's perceived authenticity of goods and services, as well as sustaining consumer relationships with businesses.
