This study aims to determine internet attitudes and internet addiction levels of 13-18-year-old students and examine the relationship between these variables. The "internet attitude scale", developed by Tavsancil and Keser (2002) and the "internet addiction scale", developed by Hahn and Jerusalem and adapted into Turkish by Sahin and Korkmaz (2011), were used as a data collection tool. The scales were applied to 286 students who were selected from secondary schools and high schools in the Kahramanmaras province. The analyses indicated that average internet attitude score of students is 3.661 and this value corresponds to the choice "I agree" in the scale. Also, it was found that average internet addiction score of students is 2.119. The findings show that the students are at the level of probable addiction in terms of tendency to internet addiction. As a result of correlation analysis, a positively significant relationship was found between internet attitude and internet addictions of the students. Also, it was determined through the regression analysis that internet attitudes of students significantly predict their internet addictions.
