Purpose: The purpose of this study is to determine whether or not the undergraduates' personality traits and self-esteem predict their forgiveness. Methods: The study was conducted using a descriptive research designed as a relational survey method. The study group consists of 323 undergraduates, of whom 250 (77.2 %) are female and 73 (22.5%) are male. The Adjective Based Personality Scale (ABPT), developed by Bacanli, Ilhan and Arslan (2009), "Rosenberg Self-Esteem Scale", developed by Rosenberg (1965) and adapted to Turkish by Çuhadaroglu (1986), and "Heartland Forgiveness Scale", developed by Thompson, Snyder and Hoffman (2005) and adapted to Turkish by Bugay and Demir (2010), were used for data collection procedure. Results: The results indicate that the undergraduates' five-factor personality traits and self-esteem are correlated with their forgiveness levels. In addition, the undergraduates' personality traits of openness, neuroticism and extraversion predict their forgiveness levels.
