Purpose: In terms of UN peacekeeping deployments, the African region has received the most, just as it has contributed the most in terms of military personnel. The Liberian UN-ECOWAS joint peace operations are acknowledged by many as one of the most successful, globally. The study argues that experiences from these operations can enrich this global effort. Hence, the study sought to establish lessons from the operations that could guide future peacekeeping operations. 
 Methodology: The study adopted a research approach that was analytical, descriptive, legal, historical and sociological; where data was mainly gathered from secondary and tertiary sources. To this end, scholarly books, edited works, articles and periodicals (duly acknowledged in the reference list) within the study area of international peacekeeping and the Liberian Civil War, were reviewed. Policy and legal documents by the United Nations (UN) and the Economic Community of West African States (ECOWAS), media stories, reports from non-governmental organizations, research reports and reports from the Liberian government in relation to the multi-functional peacekeeping operations in that country; were not left out when data was gathered for this write-up. Additionally, in terms of secondary sources, dictionaries, bibliographies, encyclopedia, databases, abstracts and indexing sources were used. 
 Findings: Main findings were that the joint operations brought lasting peace to Liberia and that lessons from those experiences have the potential of guiding future peacekeeping operations across the globe.
 Unique contribution to theory, practice and policy: The study which is useful for academic, policy-formulation and implementation purposes, recommends: that the UN Security Council institutes prompt, appropriate and adequately funded interventions that have clear, effective and purposeful mandates at the start of conflicts; ‘spoilers’, ‘trouble makers’ and warlords should be heavily sanctioned; and effective coordinative measures be put in place by the UN so as to regulate activities of Non-UN peacekeeping actors.
