- LAU is a member of the Association of American International Colleges and Universities, which facilitates student exchanges and allows for information sharing among member institutions.
- In 2006, LAU signed a ten-year memorandum of understanding with Harvard Medical International, a not-for-profit subsidiary of Harvard University, for collaboration on the development of the School of Medicine, including curriculum design and faculty development.
- The LAU libraries in cooperation with three other university libraries in Lebanon (Kaslik University, Notre Dame University and University of Balamand) established an Interlibrary Loan/Document Delivery Services consortium, called LIDS. ILL/DDS allow LAU students, faculty and staff to have access to local and overseas library resources not available at LAU.
- In March 2008, the LAU libraries became a member of Online Computer Library Center, a non-profit library service and research organization. The libraries can now borrow and lend materials on behalf of their users from and to most OCLC libraries. Also, thanks to a Libraries Very Interested in Sharing agreement signed through OCLC, LAU libraries can now share resources with more than 700 libraries around the world for free.
- The Genomics and Proteomics Research Lab, established in Byblos in 2005, is the only non-European lab to be a regular member of SeqNet.org, an initiative of 50 laboratories from 27 European countries, which aims to establish a network for sequence-based typing of microbial pathogens.
- In partnership with the United Nations Association of the United States of America, LAU has organized seven Global Classrooms–LAU Model United Nations events since 2006. The program provides knowledge and skill-based training for Lebanese and Arab students coming from diverse backgrounds in areas such as conflict resolution and civic engagement, and acquaints them with the UN procedures and rules of diplomatic and protocol representation. In May 2008, LAU introduced a new program called AL-WALID: Alpha Leadership Web for Arab Leaders in International Diplomacy, which would be sponsored by the Alwaleed Bin Talal Humanitarian Foundation.
