BAU has three alumni associations in Beirut, North Lebanon  (Tripoli), Bekaa and one in Jordan (Amman). BAU is looking to establish more chapters in many cities all over the Arab world.
The mission of the Alumni Associations is to promote the interests and welfare of BAU, its alumni, students, faculty, staff and friends. To achieve this mission, the alumni association sponsors many activities for alumni and their families.
Alumni activities include: lectures, gathering and social activities, sports, visits, seminars, field trips and professional meetings.
