ITV plc ( ) is the British media company that operates 11 of the 15 regional television broadcasters that make up the ITV Network, the oldest and largest commercial terrestrial television network in the United Kingdom. The network, which is currently branded ITV1 by ITV plc, and the independent Channel Television, has vied with the British Broadcasting Corporation's BBC One for the status of the UK's most watched channel since the 1950s (a crown it only lost in 2005). Although ITV plc has a dominant influence on the ITV Network, it should be noted that it does not form part of ITV itself, and does not actually own or operate the whole network.

ITV plc is listed on the London Stock Exchange. It was formed by the merger of Granada plc and Carlton Communications with Granada being valued about at about twice the worth of Carlton. It began trading on 2 February 2004. This was the most recent stage in a long process of mergers between the original ITV regional franchises.

ITV plc is divided into four divisions: Channels, which operates the TV networks and includes the ITV News Group, which runs the ITV regional franchises; Global Content, which is comprised of ITV Productions, the network production division, of which Granada is an on screen brand name when producing for other networks, and runs ITV's facilities businesses; Commercial, which runs ITV advertising sales arm, and Consumer, which runs itv.com, Friends Reunited and has responsibility in ITV plc shareholdings in Freeview and SDN.
