Although not new, the concept of internationalisation, the inclusion of intercultural perspectives and the development of cross-cultural understanding, has gained particular currency and support across the United Kingdom (UK) higher education sector over the last decade. However, within the academic literature, as well as within institutional policy and practice, there has been little disaggregation of the concept of "culture;" rather there appears to be a tacit belief that all aspects of students' cultures should be valued and "celebrated" on campus. Through the stories told by fifteen Sikh, Muslim, Jewish and Christian students studying at a UK post-1992 university the paper highlights the ways in which religion, a fundamental aspect of the cultural identity, values and practices of many students, is rarely recognised or valorised on campus. This lack of recognition can act to "other," marginalise and isolate students and thus undermine the aims of internationalisation, in particular cross-cultural understanding. The paper concludes by arguing that religion should be considered within debates around internationalisation so that all students are represented within a multicultural institutional ethos and to ensure meaningful cross-cultural engagement for all students.
