The Dreamcast VGA Box (also known generally as a DC VGA adapter or DC VGA cable) is an accessory for Sega's Dreamcast video game console that allows it to connect to a video display such as a computer monitor or an HDTV set through a VGA port. Because the Dreamcast hardware can produce a VGA-compatible video signal natively, this connection provides improved picture quality compared to standard composite video or S-Video connections, along with support for progressive scan video.

Sega released the original VGA Box as an official accessory, but many third-party versions were also produced and sold worldwide in various form factors.

Most games for the Dreamcast are VGA-compatible, while various workarounds exist to enable VGA output from many of the games that do not feature official support.
