iChat (previously iChat AV) is a discontinued instant messaging software application developed by Apple Inc. for use on its Mac OS X operating system. It supported instant text messaging over XMPP/Jingle or OSCAR (AIM) protocol, audio and video calling, and screen-sharing capabilities. It also allowed for local network discussion with users discovered through Bonjour protocols.

In OS X 10.8 Mountain Lion, iChat was replaced by Messages for chat and FaceTime for video calling.
