The aim of the present study is to examine the relationships among university students' participation in recreation activities, life satisfaction and happiness. The study was conducted with 460 university students based on the causal comparison pattern. The Survey of Participation in Recreation Activity, Life Satisfaction and Happiness scales were used to collect the data of the study. According to the research findings, no significant difference was found in terms of university students' life satisfaction and happiness levels depending on their participation in sports activities. On the other hand, it was observed that the happiness levels of the students who participated in social activities and those who participated in artistic and cultural activities were significantly high. Finally, significant differences were found in terms of the number of students participating in recreation activities regarding their happiness levels. [For the full proceedings, see ED626375.]
