Channel 6, also marketed as Six, is an Irish cable and satellite television operation, currently available on the Dublin, Galway, and Waterford cable systems formerly owned by NTL, the nationwide Chorus digital platform (both owned by Liberty Global), and - as of February 2007 - on Sky Digital. It is also available on some, though not every, Chorus analogue platform, including Cork, Limerick and Tralee. Since March 2007, the channel has also broadcast to a trial of 1,000 homes in counties Dublin and Louth via digital terrestrial television. Earlier, Channel 6 applied and was successful in a process to become a potential DTT 'channel manager'. The channel is encrypted and available via this method of transmission only to the trial users.

The Channel 6 website caused some confusion over the launch date. Initially the website holding image mentioned an April 2006 launch, but this referred to the launch date of the website, and not of the actual channel itself. The channel launched at 20:00 on March 30, 2006, while promotional reels began airing on NTL Digital from March 26, 2006. The website launch coincided with the programming launch and its content includes channel listings and information on the channel and its programmes.
