The Call of Duty League (CDL) represents a professional esports league dedicated to the popular video game series Call of Duty, overseen by the game's publisher Activision. Following a format similar to the Overwatch League and traditional North American professional sports leagues, the CDL features permanent, city-based teams supported by distinct ownership groups.

Unlike many other esports leagues and non-North American setups that implement promotion and relegation systems, the Call of Duty League operates on a tournament point structure and playoffs format. Players included in the team rosters are guaranteed a minimum annual salary, numerous benefits, as well as a share of winnings and revenue dependent on the team's performance.

The inception of the League was announced in 2019, and it officially launched its first competitive season in 2020.
