The Call of Duty League (CDL) is a professional esports league for the video game series Call of Duty, produced by its publisher Activision. The Call of Duty League follows the model of the Overwatch League as well as other traditional North American professional sporting leagues by using a set of permanent, city-based teams backed by separate ownership groups. In addition, the league plays in a tournament point system and playoffs format rather than the use of promotion and relegation used commonly in other esports and non-North American leagues, with players on the roster being assured benefits, and a portion of winnings and revenue-sharing based on how that team performs. The league was announced in 2019 with its inaugural season starting in 2020.

Format The Call of Duty League is owned by Activision Blizzard and is the company's second franchise-based esports league. The league plays out similar to most North American professional sports leagues, in which all teams play scheduled games against other teams to vie for position in the season's playoffs, rather than the approach of team promotion and relegation more commonly used in other esports leagues. The league currently features twelve teams.

Each match involves two teams in a best-of-five through different games based on gameplay modes and maps within the Call of Duty game. The game used depends on the most recent installment of the series, such as Call of Duty: Modern Warfare II (2022) being used for the 2023 season.

In the inaugural season, the three multiplayer modes used by the CDL include: "Search & Destroy", where one team attempts to plant a bomb and defend it at one of two control points while the other team tries to eliminate the bomb team, or if the bomb is activated, to defuse it in time; "Hardpoint", where a rotation control point appears on the map, and teams earn points for maintaining control on that point; and "Domination", where three control points appear on the map, and teams are awarded points by maintaining control of one or more of these points. In the case of "Search & Destroy" and "Domination", multiple rounds are played, switching the role of each team, while "Hardpoint" is played until a point limit is reached. Once a team has won three games in a match, the match is over, and that team given the match victory. Coaches for teams have a limited number of time outs which they can use during a game and can substitute players during this time; this is in contrast to the OWL format where play substitutions may only occur between games.

The 2020 season schedule is evenly divided into two splits for spring and summer, with a mid-season all-star event taking place after the spring split, and culminates in the Championship Weekend. Each team will host a weekend tournament-style event in their home city, and the top teams from the weekend earns points. The top eight teams at the end of season based on points claim a berth in the playoffs. A total prize pool is available to teams in the inaugural season. To standardize play at each homestand weekend, Activision constructed a transportable esports stage with input from each of the teams. To support viewership, Activision studios Infinity Ward and Beenox created a server architecture for the Call of Duty games, the CODCaster, that enables a match to be viewed from multiple different angles and identify which angles have the most exciting action to follow, as to allow the commentators and producers of the broadcast events to help show key action in the match. CODCaster also compiles key in-game statistics, and is able to render the team's characters in their team's colors for the viewing audience, though players themselves will not have this benefit.

Each team must have a minimum of seven players with a maximum of ten. Players are guaranteed a minimum salary with health and other benefits, though players may negotiate for higher salaries. At least 50% of the winnings a team earns must be shared with the team members. Players are not required to live in the city/region that the team represents. Teams are not required to providing housing for players during the season, and if they do not choose to offer it, the team must instead offer a means and stipend to help players to find such housing with approval from Activision.

Activision also established a Call of Duty Challengers series for amateur players to compete in matches and potentially be played into teams that vie for a prize pool alongside the main League season. This provides the League teams with a pool of talent that they can draw from for their teams.

Since the 2021 season, the Call of Duty League uses a 4v4 format instead of 5v5 in the previous season. "Domination" was replaced by "Control", where one team attempts to capture two points on the map, while the other team defends them. The round can end with the attackers capturing both zones within the allotted time, the defenders winning by the time expiring or by either team killing the other thirty times.

The schedule is also split into five stages, with each ending with a Major Tournament. In each stage the teams are split into groups, determined by the teams themselves, via a draft system. Every team competes in each homestand event with the finals of each event being a meeting between teams from the opposite group. During each homestand teams will earn CDL points and the top eight teams at the end of the season will enter the playoffs to compete for the CDL Championship.

Call of Duty Challengers Challengers is the amateur division of competitive Call of Duty. Challengers contains all of the up-and-coming players that are striving to enter the official Call of Duty League. The 2020 Challengers season offered a massive prize pool of $1,000,000 to be given out through a series of tournaments. The Challengers division is run through a format of "Pro points" or "Challenger points" which are virtual points given out to people based on their placing in tournaments. Owing to the vast number of people trying to make it to the Call of Duty League, it would be very difficult to find the best players without the addition of these points. This allows for franchised teams such as Optic Gaming or Seattle Surge to have academy teams equipped with the best players in Challengers. This allow for greater branding and the players based on the placing of their academy teams.

The events for Challengers are held offline in special locations. The dates of these events is in accordance to the actual Call of Duty League events. The first event of Modern Warfare was the Minnesota Launch Weekend event where there were professional pro league matches being played as well as Challengers events being held. However, before the first local area network (LAN) event during that weekend. Challengers players have to play in two online ladder tournaments to compete for Challengers points. This points are individual to each person and the sum of those points in accordance to everyone else on the team decides the seeding for the LAN events at home series events. However, in the middle of the 2020 season and beginning in the 2021 season, Challengers will be played in an online format due to the COVID-19 virus. This has changed the format to where players will play in a "Cup" or tournament every weekend in order to compete for prizes and pro points. On top of the cups, the home series events will also be played online as compared to when they were played on LAN in the beginning of the MW season.

League advertising and viewership Activision Blizzard, the publishers of the Call of Duty series launched the Call of Duty League and focused on a plan to try to make the league as presentable as possible. They first started the league by announcing a partnership with Google to allow YouTube Gaming to have exclusive streaming rights for all of their leagues.
