'''디스플레이 데이터 채널'''(Display Data Channel, '''DDC''')은 디스플레이가 지원되는 디스플레이 모드를 어댑터에 전달할 수 있도록 하고 컴퓨터 호스트가 밝기와 같은 모니터 매개변수를 조정할 수 있도록 하는 컴퓨터 디스플레이와 그래픽 어댑터 간의 디지털 통신을 위한 [[통신 프로토콜|프로토콜]] 모음이다.

최신 아날로그 VGA 커넥터와 마찬가지로 [[디지털 비주얼 인터페이스|DVI]] 및 [[디스플레이포트]] 커넥터에는 DDC용 핀이 포함되어 있지만 DisplayPort는 DVI/HDMI 모드의 옵션인 듀얼 모드 DP(DP++) 기능 내에서 DDC만 지원한다.

이 표준은 VESA([[비디오 전자공학 표준위원회]])에서 제정되었다.
