iSight is a brand name used by Apple Inc. to refer to cameras on various devices. The name was originally used for the external iSight webcam, which retailed for US$149, connected to a computer via a FireWire cable, and came with a set of mounts to place it atop any then current Apple display, laptop computer, all-in-one desktop computer, or flat surface.

Apple introduced iSight at the 2003 Worldwide Developers Conference, and It was intended to be used with iChat AV, Apple's video-conferencing client. iMovie (version 4 and later) could also be used to capture video from the device. In April 2005, Apple released a firmware update for the iSight to improve audio performance. As of October 13, 2008, the external iSight was no longer for sale in the Apple online store or in retail locations.

Meanwhile, Apple began using the term to refer to the camera built into Apple's iMac, MacBook, MacBook Air, and MacBook Pro computers, Thunderbolt Display, and Cinema Display. In November 2010, Apple began calling them "FaceTime cameras". However, the term was not retired, as the iPhone 4 and later, iPod Touch (fifth generation and later), iPad (third generation and later), iPad Mini, and iPad Pro all incorporate an “iSight” rear camera in addition to a front-facing “FaceTime” or “FaceTime HD” camera.
