ChamSys is a UK-based manufacturer of professional lighting control consoles and software, founded in 2003 by a team of lighting designers, software engineers, and hardware developers. The company name draws from the chameleon, reflecting its focus on products designed to adapt across live events, theatre, broadcast, film, houses of worship, and architectural installations. ChamSys is headquartered in England with an additional office in the United States.

The company's flagship product line is the MagicQ console series, which spans the large-format Stadium consoles (MQ500M+, MQ500M, MQ250M) and the Compact range (MQ70, MQ50), alongside the MagicQ software that also runs on personal computers. The more streamlined QuickQ series (QuickQ 10, 20, 30) targets smaller productions with a simpler touchscreen workflow. ChamSys also produces the MediaMaster media server software and the GeNetix line of DMX and network distribution hardware, covering pixel mapping, fixture control, and signal routing across a show.

ChamSys consoles are used on concert tours, stadium events, festivals, broadcast productions, and film premieres, with MagicQ often cited for its free, fully-featured software version that allows operators to program offline on a laptop before deploying to hardware.

ChamSys has 5 products cataloged on Equipboard.
