Abstract. Bullying in higher education is a form of interpersonal trauma that can have serious consequences for students' mental health, including prolonged anger, resentment, and difficulties in the forgiveness process. Forgiveness is essential to prevent the long-term psychological consequences of traumatic experiences, and one psychological factor that may facilitate forgiveness is post-traumatic growth (PTG). This study aimed to examine the effect of post-traumatic growth on forgiveness among university students who have experienced bullying. The study employed a quantitative approach using a predictive correlational design. A total of 122 university students with experiences of bullying were selected through purposive sampling. The instruments used were an adapted version of the Post-Traumatic Growth Inventory (PTGI) based on the theory of Tedeschi and Calhoun, and the Transgression-Related Interpersonal Motivations (TRIM-18) scale based on McCullough's theory. The categorization results indicated that both post-traumatic growth and forgiveness were at high levels. The findings revealed a positive and significant effect of post-traumatic growth on forgiveness (B = 0.332, p < .001, and R2 = 0.125), with post-traumatic growth accounting for 12.5% of the variance in forgiveness. These findings suggest that higher levels of post-traumatic growth are associated with higher levels of forgiveness among university students who have experienced bullying. Therefore, post-traumatic growth serves as an important psychological factor that facilitates the forgiveness process among victims of bullying in higher education Abstrak. Perundungan di perguruan tinggi merupakan bentuk trauma interpersonal yang berdampak serius terhadap kesehatan mental mahasiswa, termasuk munculnya kemarahan berkepanjangan, dendam, dan hambatan dalam proses pemaafan. Kemampuan pemaafan dibutuhkan agar dampak traumatis tidak berkelanjutan, dan salah satu faktor yang diduga dapat memfasilitasinya adalah post-traumatic growth (PTG). Penelitian ini bertujuan untuk mengetahui pengaruh post-traumatic growth terhadap pemaafan pada mahasiswa korban perundungan. Penelitian ini menggunakan pendekatan kuantitatif dengan predictive correlational design. Sampel diperoleh melalui teknik purposive sampling dengan jumlah 122 mahasiswa korban perundungan. Alat ukur yang digunakan dalam penelitian ini adalah adaptasi Post-traumatic growth Inventory (PTGI) yang didasari oleh teori Tedeschi & Calhoun dan skala Transregression-Related Interpersonal Motivation (TRIM)-18 yang didasari oleh teori Mccullough. Hasil kategorisasi menunjukkan bahwa post-traumatic growth dan pemaafan berada pada kategori tinggi. Hasil uji menunjukkan terdapat pengaruh positif dan signifikan post-traumatic growth terhadap pemaafan (B = 0.332, p < 0.001, dan R2 = 0.125) dengan kontribusi sebesar 12.5% terhadap pemaafan. Temuan ini menunjukkan bahwa semakin tinggi tingkat post-traumatic growth yang dimiliki mahasiswa korban perundungan, maka semakin tinggi pula pemaafan, sehingga post-traumatic growth berperan sebagai salah satu faktor psikologis penting dalam memfasilitasi proses pemaafan pada korban perundungan di perguruan tinggi.
