Tobacco consumption among adolescent students in Nepal has grown to an alarming proportion, raising serious concerns about associated factors. The study aimed to describe the tobacco consumption behavior of in-school adolescent students and its associated factors. A cross-sectional survey design was followed to conduct the study. Students of community schools in Class 10 of a municipality in Saptari, Nepal, were the population of the study. All students who were present on the day of data collection participated in the study. Two hundred and twenty-five students participated in the study with a response rate of 95.74%. A validated, self-administered anonymous questionnaire was used to collect data. Frequency, percentage, and binary logistic regression were used to analyze the data. The proportion of students who consumed tobacco was 24% (boy: 18.7%, girl: 5.3%). Sex of students (OR = 5.529, 95% CI 2.375–12.872, P = .000) and tobacco consumption behavior of students’ fathers (OR = 3.358, 95% CI 1.308–8.617, P = .012) were significantly associated with tobacco consumption behavior of adolescent students. I concluded that the sex of students and the tobacco consumption behavior of students’ fathers are the main associated factors of the tobacco consumption behavior of adolescent students. Anti-tobacco policies should be developed and implemented with the coordination of school administration, the school management committee, and the local bodies targeting students, especially boys and students’ fathers.
