This study delved into the development of Global Citizenship among junior high school students and its relationship on their Intercultural Communication Skills. To investigate this relationship, a survey instrument was administered to 100 junior high school students from Libertad National High School, utilizing a simple random sampling method. Data were analyzed using statistical tools, including mean, Pearson- r, and regression analysis. The findings reveal that while students exhibit moderately extensive intercultural communication skills, their global citizenship development varies across dimensions. Cultural awareness and social responsibility were found to be rarely extensive, while empathy and respect, along with a global perspective, demonstrated moderately extensive levels. A strong relationship exists between Global Citizenship Development and Intercultural Communication Skills, emphasizing the interconnectedness of these constructs. Furthermore, specific indicators, such as empathy and global perspective, significantly influence students' intercultural communication abilities. This study suggests the importance of targeted educational interventions aimed at enhancing cultural awareness, social responsibility, empathy, and a global perspective among junior high school students. Future researchers may explore innovative teaching methods to further develop students' global citizenship and intercultural communication skills.
