The website has been designed and produced by digital agency Lateral and technical firm NeoWorks.
It will support key strands and programmes on the channel including Five Movies, 'Milkshake', 'The Wright Stuff', 'Terry & Gaby', 'Home & Away', 'Family Affairs' and 'House Doctor'.
Links to the official sites of Five's acquired American shows, including 'CSI', are available, while news and weather updates continue to be provided by ITN. A text-only version of the site is also on offer.
David Pullan, Five's director of strategy and marketing, said: "The new-look Five website reflects the channel's identity and offers users a rewarding online destination which is lively, accessible and fun to use."
