The Big Breakfast is a British breakfast light entertainment television programme that was broadcast on Channel 4 from 1992 to 2002, and as a revival from 2021 to 2022. The show had various presenters, starting with Chris Evans and Gaby Roslin at launch with the revival episodes presented by Mo Gilligan and AJ Odudu.

The programme was distinctive for broadcasting live from a real house (which had been lock-keepers' cottages), commonly referred to as "The Big Breakfast House", or more simply, "The House", located on Fish Island, in Bow in east London. The original house on Fish Island in Bow has since been sold.

The show was a mix of news, weather, interviews, audience phone-ins and general features, with a light tone which was in competition with the maturer GMTV and BBC Breakfast programmes.

The Big Breakfast was launched on 28 September 1992 to replace The Channel Four Daily, which was Channel 4's unsuccessful first foray into the breakfast television market. The Daily, which had focused on current affairs and news bulletins alongside bitesized magazine shows, a quiz show segment and a daily cartoon slot, had failed to attract enough viewers so Channel 4 opted to change direction and work towards a lighter style concentrating mainly on entertainment and humour with news bulletins restricted to brief summaries every 20 minutes.

The first two presenters were Chris Evans (from 1992 to 1994) and Gaby Roslin (1992 to 1996). At its height in 1993, viewing figures reached around two million per edition, and it was the highest rated UK breakfast television programme. Along with Evans and Roslin, Bob Geldof presented a short-lived political interview slot. His wife Paula Yates interviewed people whilst lying on a bed, and the puppet characters Zig and Zag created morning mayhem in the bathroom with Evans in a slot called 'The Crunch'.

As part of his contract with The Big Breakfast, Evans was committed to developing a new show for Channel 4. Don't Forget Your Toothbrush began in early 1994, and Evans cut his involvement with The Big Breakfast to three days a week, Tuesday to Thursday. Neighbours actor Mark Little replaced Evans on Mondays and Fridays. When Evans left the show later that year, Little continued Thursdays, and Fridays while Paul Ross took over Mondays to Wednesdays. Richard Orford replaced Ross around Easter 1995 but was quickly dropped and exchanged with Down Your Doorstep presenter Keith Chegwin. In July 1995, the show reverted to using just one male presenter (Mark Little) throughout the week. Chegwin would cover for Little when he was on tour as a comedian or on holiday. Roslin would be covered by Australian singer/actress Dannii Minogue when she was on breaks from the show.

Roslin continued full-time until she made way for Zoe Ball in 1996. Audience figures dropped a little after Evans left, and a little further after Roslin departed. Mark Little left the programme in July 1996, following press reports that he and Ball had fallen out. Little was replaced by Keith Chegwin, who himself exited the programme in August 1996, just ahead of a relaunch. To stem the sliding viewing figures, the Big Breakfast house was refurbished at a cost of £2 million. New presenters Rick Adams and Sharron Davies were brought in but viewing figures fell dramatically. Davies left the programme in early 1997, to be replaced by Denise van Outen. Van Outen had initially been brought in as part of the September 1996 relaunch as a weather presenter, before being given a role based at the house as the phone room presenter and holiday relief for Davies. In June 1997, Johnny Vaughan covered for Adams for a fortnight alongside Van Outen, the pair forging a successful on-screen partnership. Adams left the programme shortly afterwards and, in September 1997, the Vaughan and Van Outen partnership was made permanent. Audience figures stabilised and the duo fronted the programme together until Van Outen's departure on 1 January 1999 (a New Year's Day pre-record). Kelly Brook was installed as Vaughan's new co-presenter despite an internet campaign for the role to be awarded to Liza Tarbuck, who had successfully covered for Van Outen in the summer of 1998. However, Brook struggled in the role and left the programme in early summer 1999. Liza Tarbuck, having again covered the co-presenter role alongside Vaughan prior to Brook's departure, was made permanent at the end of August 1999. She left the following summer and, following Vaughan's annual one-month summer break, Denise van Outen returned to co-host in September 2000 for Vaughan's final four months on the programme. Vaughan and Van Outen's final Big Breakfast was on 12 January 2001.

The programme relaunched with a new logo and updated theme on 22 January 2001. The house had also been redecorated in more muted colours, echoing the ill-fated 1996 revamp. The programme moved to a lineup of three main presenters: Paul Tonkinson, Amanda Byram and Donna Air. However, Tonkinson was dropped from the programme at the end of March 2001 and Air left not long after. The programme reverted to two main presenters once more, with Byram and Richard Bacon. The living room, which had been repainted a dark red as part of the revamp, was changed to a bright yellow and pink design, while the main presenter chairs were also reinstalled in front of the living room's French windows. They replaced the bright-green sofa which had also been brought in as part of the revamp. The new logo was replaced with one more closely resembling the traditional Big Breakfast logo, albeit utilising a slightly different font. Mike McClean was given a role on the programme, as Down Your Doorstep presenter and cover for Bacon, most regularly on Fridays when Bacon would reprise his former Down Your Doorstep role alongside Johnny Vegas. During this time, a pilot episode was filmed on a Saturday with Chris Moyles and Dominic Byrne (reading the news), with Andy Goldstein doing links from Los Angeles. This pilot episode was shown to bosses at Channel 4, after which Moyles was offered the role but declined.
