The aim of the study was to determine the relationsip between deontic justice attitudes among prospective teachers and their tendencies towards academic dishonesty. Participants in the study were 403 university students attending different departments of the Education Faculty of the Hacettepe University, a state university in the Central Anatolia Region of Turkey. The sample was determined by means of a stratified sampling technique, and students were chosen randomly from different departments. Attitudes towards deontic justice and tendencies towards academic dishonesty among the participants were stratified in terms of gender and students' affiliation to a specific department of education. The findings suggested that female students and participants from the English Language Education Department had the highest deontic justice attitudes; male students and participants from the Physical Education and Sports Department had the highest tendencies towards academic dishonesty. A low, negative and statistically significant relationship between deontic justice attitudes and academic dishonesty tendencies exists.
