The impact of sports events is reflected in many effects, not only by attracting a number of participants and visitors, but also by directing an economic impact. The effects of major sports events can be extremely successful or unsuccessful in terms of economic or other targeted results, but the positive effects are reflected in the extent to which the sports event contributes to social, cultural and economic development. Also, major sports events have their impact on environmental development, health and hygiene conditions, as well as opportunities to start or accelerate direct and indirect economic and other activities. The aim was to define and present the effects of top sports events. It can be concluded that, regardless of the indicators of the events themselves, the contributions to the economy and other areas are numerous and most often positive, which is why a large number of countries/cities tend to organize large sporting events. It can be said that every major sports event organized so far, regardless of the final financial outcome, implied a large number of benefits for the organizer country/city.
