This study investigates the impact of knowledge sharing and a creative work climate on teachers' innovative behavior in Cirebon, Indonesia. Using a quantitative approach through survey methods, data were collected from 122 teachers selected using Stratified Random Sampling to ensure accurate sample representation. The results show that knowledge sharing is the strongest predictor of teachers' innovative behavior, indicating that teachers who actively exchange ideas and teaching strategies are more likely to adopt innovative teaching methods. Additionally, the creative work climate also positively influences teacher innovation, although the effect is moderate, suggesting the presence of other contextual factors. These findings highlight the urgency of building a collaborative and supportive school environment for creativity to enhance teachers' innovation capacity. The practical implications of this research are expected to serve as a guide for policymakers and school administrators in designing strategies that encourage a culture of knowledge sharing and creativity-based professional development among educators.
