The Macintosh Quadra 840AV is a personal computer designed, manufactured, and sold by Apple Computer from July 1993 to July 1994. It was introduced alongside the Centris 660AV, where "AV" signifies audiovisual capabilities, such as video input and output, telecommunications, speech recognition, and enhanced audio. The 840AV has the same mini-tower form factor as the Quadra 800, with a faster Motorola 68040 processor.

The Quadra 840AV was discontinued shortly after the introduction of the PowerPC-based Power Macintosh. The Power Macintosh 8100/80AV provides the same functionality in the same form factor, and had a significantly higher price point. The 7100/66AV was priced comparably to the 840AV but in a IIvx-style desktop case.
