Internet addiction has attracted significant attention due to its adverse effects on humans, especially young people. This study is aimed at investigating the impact of emotional intelligence on Internet addiction. Data was collected from 744 Vietnamese students in Vietnam. SPSS 20.0 software was used for descriptive statistics, reliability testing, factor analysis, and regression. The empirical results showed that emotional intelligence had a negative influence on Internet addiction. Specifically, the components self-emotion appraisal (SEA), others’ emotion appraisal (OEA), and regulation of emotion (ROE) significantly affected Internet addiction. However, the effect of the component use of emotion (UOE) on Internet addiction was not found to be statistically significant. Overall, the results of the study indicate that improving emotional intelligence may reduce the extent of Internet addiction among Vietnamese students.
