Call of Duty HQ, often shortened to "COD HQ" and stylized as simply "Call of Duty", is a game launcher designed by Infinity Ward that was released on October 28th, 2022. It serves as a centralized launcher for every Call of Duty game since Call of Duty: Modern Warfare II, including Call of Duty: Warzone.

Call of Duty HQ is the front door for Call of Duty across all console and PC platforms. Within Call of Duty HQ, players have control over the footprint of their Call of Duty experience on their platform of choice, and it's all contained within one unified location.

On July 29th, 2025, Call of Duty: Modern Warfare II and Call of Duty: Modern Warfare III became standalone titles, and were removed from the launcher.
