This study aimed to determine the digital addiction levels of secondary school students who do and do not do sports. Ethics committee approval was received for the research.  The study group consists of a total of 520 people, 259 girls and 261 boys, studying in secondary school. To obtain the data, a personal information form and the digital addiction scale for children, developed by Hawi et al., (2019) and Kaçmaz et al., (2023), whose Turkish validity and reliability study was conducted, were used. Variance and homogeneity of the obtained data were tested, Independent t test was used for pairwise comparisons, and One Vay Anowa test was used for multiple comparisons. As a result of the analysis, no differences were detected in the participants' digital addiction levels depending on gender, class, mother's education level and father's education level(p >0,05). A significant difference was detected in the digital addiction levels of the participants according to their sports activities (p<0.05). It has been observed that individuals who do sports have lower average scores than those who do not do sports. Today, excessive use of internet-connected technological devices such as smartphones, computers or tablets is thought to cause digital addiction in children.
