This grounded theory study explored the conceptualization of authenticity in language education. The participants were 30 Iranian English language educators, who were studied as adult learners. The findings revealed that authenticity was conceptualized by language educators as a social and reflective practice under the influence of the instructions of Islam and the collectivist culture of Iran as a country in the Middle East. Three main themes were identified as follows: three-way pedagogical relationship, reflectivity, and context-appropriate adjustments. Three-way pedagogical relationship addressed educators' learning experiences, subjects driven from the context, and the importance of learners. Also, reflectivity included reflection on content, process, and premise. Furthermore, context-appropriate adjustments referred to the disagreement with conformity to educational systems encouraging nativeness. Indeed, the participants conceptualized authenticity as finding one's own voice in the midst of the dominant native voices, while reflecting on one's own pedagogical practices and respecting one's own religion and context.
