In this article, we discuss the position of Finnish constitutional bilingualism in higher education in the context of internationalisation in English, by focusing on two universities: one dominantly monolingual (Finnish), one dominantly bilingual (Finnish–Swedish); in addition, both teach in English. This article investigates how discourses around language choices (language policy documents, selected staff and student interviews) construe these universities as monolingual, bilingual or trilingual, and what these discourses say about the universities as organisations themselves. Results suggest that, although lack of clarity remains regarding language choices in many practical situations, Finnish and English are seen as self-evident primary languages of the universities; Swedish, as the third language, occupies a more contested place.
