The purpose of this study is to determine the relationship between student cynicism and students' life satisfaction. This study is in correlational survey model. The sample of the study consists of 554 Turkish high school students, who were selected by simple random sampling method. Findings show that female students have more cynical attitudes towards their schools than male students. And, female students are less satisfied with their school and living environment but more satisfied with their friends than male students. Students who think about studying at another school have higher levels of student cynicism but lower levels of school satisfaction and living environment satisfaction than those who do not think so. The findings reveal the negative relationships between student cynicism and students' life satisfaction. The strongest relationship has been determined to be between institutional cynicism and reduced sense of school satisfaction. Path analysis indicates that four subscales of student cynicism affect students' life satisfaction. It is possible to examine the premises that lead to the perception of student cynicism and their impacts. For future research, it is recommended to examine the ways to alleviate the negative effects of student cynicism and improve the outcomes.
