The aim of the study is to assess the impact of crowd management strategies on corporate sponsorship sustainability of organized sports competitions in Lagos state. The cross-sectional research method was adopted for this study. The population for this study included sports administrators, facility managers, sports media houses and corporate organizations in Lagos state. The study comprised a sample of four hundred and eighty-nine (489) respondents comprising of 348 sports administrators, 63 facility managers and 78 sports media houses in Lagos state. The multistage sampling technique was used to select respondents for this study. The sampled sports and corporate organizations are those that are established on a well-structured administrative set up. A self-developed research questionnaire named “Crowd Management Impact and Sponsorship Sustainability Questionnaire” (CMISSQ) was used for this study. The questionnaire had a reliability coefficient of 0.87. The descriptive statistics of bar chart was used to present the demographic data. The inferential statistics of multiple regressions was used to test the stated null hypothesis at a 0.05 alpha level using the statistical tool for Social Sciences (SPSS). Results indicated that ticketing strategy, seating arrangement has significant impact on corporate sponsorship sustainability of organized sports competitions in Lagos state. Entry and exit points also significantly affect corporate sponsorship sustainability of organized sports competitions in Lagos state. The study recommended that advance selling of tickets should be employed as this saves times and ensures that overcrowding of fans and spectators at ticket selling booths. This reduces congestion in the interior area in the search for the correct seat. For high-risk matches, opposing fans should be strictly separated by allocating sectors other than those indicated on the match tickets (enforced segregation), or by creating and reserving empty stadium sectors between ‘dangerous’ spectator sectors. Reserved seating should be strongly considered as the only seating allowed for those events that attract excitable and competitive crowds.
