In Kulon Progo Regency, the prevalence of anemia is 43.67%, with the highest prevalence found in Nanggulan District at 64%, despite the coverage of Iron Supplementation Tablets (IST) reaching 100%. This condition highlights the importance of behavioral factors, particularly knowledge, in preventing anemia. Peer Group Education was selected as an educational approach because it actively involves peers and is appropriate for adolescent characteristics. Objective: To determine the difference in adolescent girls' knowledge regarding anemia prevention before and after Peer Group Education at SMK Negeri 1 Nanggulan, Kulon Progo. Methods: This quantitative study employed a pre-experimental one-group pretest–posttest design involving 42 female students selected using proportional stratified random sampling. Knowledge was measured using an anemia prevention questionnaire administered before and after the intervention. Data were analyzed using the Wilcoxon Signed Rank Test, Spearman Rank correlation test, and Mann–Whitney test. Result: Most respondents were 17 years old (40.5%). The mean knowledge score increased from 15.24 before the intervention to 24.69 after the intervention. The Wilcoxon Signed Rank Test showed a significant difference in knowledge before and after the intervention (p=0.000). Age was significantly associated with the improvement in knowledge (r=0.364; p=0.018), whereas previous experience of attending health education sessions was not significantly associated with knowledge improvement (p=0.237). Conclusion: Peer Group Education was effective in improving adolescent girls' knowledge regarding anemia prevention.
