Call of Duty is a military video game series and media franchise published by Activision, starting in 2003. The games were first developed by Infinity Ward, then by Treyarch and Sledgehammer Games. Several spin-off and handheld games were made by other developers. The most recent title, Call of Duty: Modern Warfare III, was released on November 10, 2023.

The series originally focused on a World War II setting, with Infinity Ward developing Call of Duty (2003) and Call of Duty 2 (2005) and Treyarch developing Call of Duty 3 (2006). Call of Duty 4: Modern Warfare (2007) introduced a modern setting, and proved to be the breakthrough title for the series, creating the Modern Warfare sub-series; a Modern Warfare remastered version released in 2016. Two other entries, Modern Warfare 2 (2009) and Modern Warfare 3 (2011), were made. The sub-series received a reboot with Modern Warfare in 2019, Modern Warfare II in 2022, and Modern Warfare III in 2023. Infinity Ward have also developed two games outside of the Modern Warfare sub-series, Ghosts (2013) and Infinite Warfare (2016).

Treyarch made one last World War II-based game, World at War (2008), before releasing Black Ops (2010) and subsequently creating the Black Ops sub-series. Four other entries, Black Ops II (2012), Black Ops III (2015), Black Ops 4 (2018), and Cold War (2020) were made, the latter in conjunction with Raven Software. Sledgehammer Games, who were co-developers for Modern Warfare 3, have also developed three titles, Advanced Warfare (2014), Call of Duty: WWII (2017), and Vanguard (2021). They are also the lead developer for Modern Warfare III (2023), the third entry in the Modern Warfare reboot sub-series.

As of October 2023^[update], Call of Duty has sold over 425 million copies.^[1] The series is verified by the Guinness World Records as the best-selling first-person shooter game series. It is also the most successful video game franchise created in the United States and the fourth best-selling video game franchise of all time. Other products in the franchise include a line of action figures designed by Plan B Toys, a card game created by Upper Deck Company, Mega Bloks sets by Mega Brands, and a comic book miniseries published by WildStorm Productions, and a feature film in development.
