This study analyses Spanish undergraduate and postgraduate students' sense of European identity. It examines the role of international study programmes (ISPs) and plurilingualism (students' mastery of one or more foreign language) in 871 students' perception of their European identity, attachment to Europe, and perception of the European Union (EU). Findings show that students participating in or interested in ISPs have a more positive view of Europe and the EU. Conversely, non-mobile students tend to exhibit stronger local identities and view Europe more neutrally or negatively. Students with broader language repertoires (those speaking more than one foreign language) are more likely to associate the EU with positive aspects, such as cultural diversity. However, students primarily speaking Spanish often connect the EU to challenges like unemployment. Proficiency in multiple European languages emerges as a key factor in fostering a positive European orientation.
