Eshref Ademaj (1940–1994) was a Yugoslav mathematician and education activist of Albanian ethnicity. A professor of the University of Pristina, he played a pivotal role in the early restoration of universitarian activity in Kosovo after the mass dismissals of academicians and ban of Albanian language education by the Serbian government of Slobodan Milošević in the early 1990s. Ademaj was also a corresponding member of the Academy of Sciences and Arts of Kosovo.
