Nomophobia, a newborn concept that has become an important part of our lives in recent years due to effective use of smart phones in daily life, can be defined as "fear of staying away from smart phones". The aim of this study was to determine the nomophobia level of 8th grade students and to determine whether the nomophobia levels of the students differ according to the variables such as gender, overall grade point average, parental education status, parental profession, and monthly income of the family. In this quantitative research, cross-sectional survey research model was used. "Nomophobia Scale" developed by Yildirim and Correia (2015) and "The Demographic Information Form" were used as data collection tools. According to the findings; the nomophobia levels of 8th grade students did not differ by gender of the students, overall grade point average, educational status of the parents, profession of the parents and monthly financial amount of the family.
