In Australian rules football, the AFL Grand Final, held annually at the Melbourne Cricket Ground, draws approximately 100,000 spectators, making it the world's highest attended league championship event.

This article lists the attendance of many sports competitions around the world, based in some cases on the number of tickets sold or given away, rather than people actually present. The list is almost exclusively stadium field and indoor arena ball sports. Top leagues in weekly attendance includes speedway sports.

All listed attendance figures reflect those for the most recent season or event for which:

• reliable attendance figures are available, and for UK Boxing events 2019.
• no artificial attendance restrictions (i.e., apart from venue capacity) were imposed during the relevant time frame—an entire season or a given event, as applicable.

Top leagues in recent domestic club championship event attendance

The annual UAAP Cheerdance Competition routinely sells out the Smart Araneta Coliseum, Southeast Asia's largest indoor arena.

This section lists the most recent attendances at annual championship events (single decider matches or the final match in a best-of series only) by total attendance; however, be advised that figures affected by the COVID-19 pandemic have not been included. It also includes domestic leagues and competitions. Additionally, it includes the finals of top-level promotion playoffs, in which teams play to determine potential or confirmed promotion to a country's top league level in the next season. It has to be noted that the listed crowd figures are often a reflection of a championship venue's capacity, as demand for these events is generally so high that any stadium or arena would be filled to capacity.

For the purposes of this table, "domestic" is defined to include leagues which are historically focused in one country, but may have teams in one or more nearby countries.

The EuroLeague in basketball is transnational in that it includes teams from multiple European countries, but is domestic in the sense of being a championship for the single entity of Europe. It is governed by Euroleague Basketball, an explicitly pan-European body that is independent of the continental governing body of FIBA Europe.

This contrasts with leagues such as Super Rugby and the URC, which operate in multiple countries with more than one team in most (Super Rugby) or all (URC) of their participating countries, and also make no pretense of being a championship for a continental-size region.

Semi-professional and amateur leagues

This section lists college and amateur leagues by total attendance. Remaining amateurism requirements in the majority of top-level sports were dropped in the late 20th century, and there are now only a few amateur leagues which are of interest to a wide public. In the United States, college sports are very popular and at least one significant ice hockey league retains an amateur requirement. In Ireland, the All-Ireland senior championships in Gaelic football and hurling, both operated by the Gaelic Athletic Association, which continues to prohibit professionalism, each draw over 80,000 to fill Croke Park for the respective finals.^[190]

The NCAA championships listed here are all composed of several separate conferences with varying attendance levels. For example, in American football, per-game home attendances for the highest level of competition, Division I FBS, in the 2018 season ranged from 15,458 for Mid-American Conference teams to 73,994 for Southeastern Conference teams.^{[191][Note 2]} NCAA Division I FBS football has the 2nd highest average attendance worldwide for any league-wide sport (behind the National Football League) and the 2nd highest overall attendance worldwide (behind Major League Baseball). For college baseball, Dudy Noble Field, Polk-DeMent Stadium at Mississippi State University holds the on-campus attendance record at 15,586^[192] and all of college baseball's Top 11 on-campus largest crowds.

Representative matches

This list covers special annual matches for representative sides that are not covered elsewhere by international or domestic fixtures. They include state or regional matches, annual commemorative games and publicly voted all-star selections. This type of event is unknown within European nations, except in basketball; many European domestic leagues in that sport hold an all-star game at roughly the midpoint of the regular season.

International club competitions

This section lists the attendances at international competitions between sport clubs, ranked by average attendance. These are usually organised on a continental basis. The teams which compete in these tournaments also compete in the domestic competitions in their home countries.
