TF1 is a national French TV channel, controlled by TF1 Group, whose major share-holder is Bouygues. TF1's average market share of 24% makes it the most popular domestic network.

TF1 originally stood for "Télévision Française 1" (French Television 1). Since its privatisation in 1987, the abbreviation is no longer expanded, so as to avoid confusion with the government-owned channel France Télévisions.

The channel is part of the TF1 Group of mass media companies, which also includes the news channel LCI and Eurosport, the largest European sports network. Together with France Télévisions, TF1 co-managed the international French news channel France 24 but has since sold its share.

TF1 is a supporter of the Hybrid Broadcast Broadband TV (HbbTV) initiative (a consortium of broadcasting and Internet industry companies including SES Astra, OpenTV and Institut für Rundfunktechnik) that is promoting and establishing an open European standard for hybrid set-top boxes for the reception of broadcast TV and broadband multimedia applications with a single user interface.
