Since its launch in 1982, Channel 4 has used the same logo which consists of a stylised numeral "4" made up of nine differently-shaped blocks.

The original version was designed by [[Martin Lambie-Nairn]] and his partner Colin Robinson and was the first UK channel ident made using advanced computer generation (the first electronically generated ident was on [[BBC Two "Computer Generated 2" ident|BBC2 in 1979]], but this was two-dimensional). It was designed in conjunction with Bo Gehring Aviation of Los Angeles and originally depicted the "4" in red, yellow, green, blue and purple. The music accompanying the ident was called "Fourscore" and was composed by David Dundas; it was later released as a single alongside a B-side, "Fourscore Two", although neither reached the UK charts. In November 1992, "Fourscore" was replaced by new music.

In 1996, Channel 4 commissioned Tomato Films to revamp the "4", which resulted in the "Circles" idents showing four white circles forming up transparently over various scenes, with the "4" logo depicted in white in one of the circles.

In 1999, Spin redesigned the logo to feature in a single square that sat on the right-hand side of the screen, whilst various stripes would move along from left to right, often lighting the squared "4" up. Like the previous "Circles" idents from 1996 (which was made by Tomato Films), the stripes would be interspersed with various scenes potentially related to the upcoming programme.

The logo was made three-dimensional again in 2004 when it was depicted in filmed scenes that show the blocks forming the "4" logo for less than a second before the action moves away again.

In 2015, a new presentation package by the network's in-house agency 4Creative was introduced. Directed by filmmaker [[Jonathan Glazer]], the "4" logo itself was downplayed on-air in favour of idents and bumpers featuring the individual blocks as objects, including idents depicting them as "[[Kryptonite]]"-like items of fascination (such as being excavated, and viewed under a [[microscope]] for scientific study) that reflect Channel 4's remit of being "irreverent, innovative, alternative and challenging". Musician [[Micachu]] composed music for the idents.<ref>{{cite web |title=New Channel 4 identity by creative dream team of 4Creative, Jonathan Glazer, Neville Brody and DBLG |url=https://www.itsnicethat.com/articles/channel-4-neville-brody-jonathan-glazer-rebrand |access-date=9 August 2024 |website=www.itsnicethat.com }}</ref> This theme continued in 2017, with new idents by [[Dougal Wilson]] that focused on an [[anthropomorphic]] "giant" constructed from the blocks, and its interactions in everyday life. A new acoustic rendition of "Fourscore" was also composed for the idents.<ref>{{cite web |title=How Channel 4 built a disruptive giant that represents everything about the brand |url=https://www.campaignlive.co.uk/article/channel-4-built-disruptive-giant-represents-everything-brand/1449061 |access-date=18 June 2023 |website=www.campaignlive.co.uk }}</ref>

In September 2018, all of Channel 4's digital channels underwent a rebranding by ManvsMachine and 4Creative, including new logos that incorporate variants of the Lambie-Nairn "4". The rebranding was intended to give Channel 4's family of services a more uniform brand identity, while still allowing room for individualized elements that reflect their positioning and programming.<ref>{{cite web |last=McCarthy |first=John |title=Channel 4 airs 'eclectic, unpredictable' rebrand across all of its channels |url=https://www.thedrum.com/news/2018/09/27/channel-4-airs-eclectic-unpredictable-rebrand-across-all-its-channels |access-date=9 August 2024 |website=The Drum}}</ref>

The original 1982 ident was given a one-off revival on 28 December 2020, as a tribute to Lambie-Nairn after his death three days earlier.<ref>{{cite web |date=28 December 2020 |title=Channel 4 Ident – Martin Lambie-Nairn tribute – 28/Dec/2020 |url=https://www.youtube.com/watch?v=RUH1dZZ4xrg |url-status=live |archive-url=https://ghostarchive.org/varchive/youtube/20211124/RUH1dZZ4xrg |archive-date=24 November 2021 |accessdate=13 April 2021 |work=YouTube}}{{cbignore}}</ref> It was also used on 22 January 2021 as part of the 80s-themed "takeover" to promote the premiere of ''[[It's a Sin (TV series)|It's a Sin]]'', which was set during the 1980s [[HIV/AIDS in the United Kingdom|AIDS crisis]].<ref>{{cite web |date=3 January 2022 |title=Channel 4: It's A Sin campaign |url=https://www.creativereview.co.uk/channel-4-its-a-sin-campaign/ |access-date=13 July 2023 |website=Creative Review }}</ref>

To mark the network's 40th anniversary, Channel 4 began to phase in another rebranding in November 2022, and announced that new idents were being produced that would be "an unexpected and daring portrait of Britain retold". In an effort to emphasise its digital platforms, it was announced that the "All4" branding would be dropped from Channel 4's video on-demand platform, in favour of marketing it under the "Channel 4" name with no disambiguation.<ref>{{cite web |last=Ramachandran |first=Naman |date=2 November 2022 |title=Channel 4 Rebrands VoD Service All4 as Channel 4 |url=https://variety.com/2022/tv/global/channel-4-all4-rebrand-1235420832/ |access-date=9 August 2024 |website=Variety }}</ref> The new idents, "Modern Britain", premiered in June 2023, featuring looping cycles of themed scenes built around the Channel 4 logo by various artists.<ref>{{cite web |last=Kiefer |first=Brittaney |date=14 June 2023 |title=Channel 4's Idents Are Public Art Capturing Modern Britain |url=https://www.adweek.com/creativity/channel-4-new-idents-capturing-modern-britain/ |access-date=9 August 2024 |website=www.adweek.com }}</ref>
