This paper addresses the issue of religious young people concealing their religious identity in their daily lives outside the family. Although it is observed that the research topic is a patterned phenomenon today, there is no study directly related to the subject in the literature. The aim of the research is to understand the reasons why young people whose families are religious conceal their religious identities in their daily lives outside the family and their experiences and thoughts on this issue. The purpose of understanding requires analysing the perspectives and experiences of the young people at the focus of the study. This requirement has influenced the determination of the method and technique used in the research. In this regard, a qualitative research method based on the interpretive social science method was used in the research. The interpretive approach was preferred because it aims to examine how people construct meanings in their everyday lives and what is meaningful or important to them. The issues considered in the research method and approach were also taken into account when selecting the research design; the phenomenological design, which focuses on phenomena that are known but require in-depth knowledge, was preferred. The sample of the research consists of young people with a religious identity whose families are devout. Participants were determined using two sampling methods. First, it was decided to use purposive sampling to reach the participants. The reason for choosing purposive sampling was the belief that the phenomenon of concealing religious identity cannot be easily detected by an outside observer. Therefore, preliminary interviews were conducted with young people whose families are religious and who are thought to conceal their religious identity in their everyday lives, and a sample pool was created. Another sampling method used in the study was the snowball sampling model. The snowball sampling model was preferred in order to more easily reach young people who were thought to conceal their religious identity, based on the people who participated in the study. When creating the sample, the criteria were set as participants being between the ages of 18 and 30 and living with their families. The data were obtained from interviews conducted with 19 participants between April and July 2023. The data were analysed using the MAXQDA programme based on an interpretive-understanding sociological perspective. The findings of the study reveal that young people conceal their religious identity in social environments outside their family circle due to various concerns. These concerns include the association of Islam with backwardness and the past, fear of marginalisation and exclusion, anxiety about being stigmatised or associated with certain stereotypes, the risk of being misunderstood, and sensitivity regarding the responsibility of representation. In response to these concerns, young people have developed tactics in their everyday lives, as conceptualised by Michel de Certeau. The study explains these practices, which young people adopt to make their religious identities invisible, with the conceptualisation of ‘secular masks of religious identity.’ Young people wear secular masks in various places, such as their circle of friends, which constitute the front stage in Goffman's terminology, but when they go behind the scenes, they take off their secular masks. Thus, the secular masks of religious identity represent tactics developed in response to strategies in de Certeau's sense. Strategies create anxieties that arise during young people's interactions in their peer groups; in response to these anxieties, secular masks emerge as tactics.
