Leigh Izaak Francis (born 30 April 1973), who is often known by the name of a character he plays, Keith Lemon, is an English television presenter, comedian, actor, and writer. He is best known for creating and starring in Channel 4's sketch comedy show Bo' Selecta! (2002–2009) and presenting the ITV shows Celebrity Juice (2008–2022) and Through the Keyhole (2013–2019). His other comedy shows include Lemon La Vida Loca (2012–2013), The Keith Lemon Sketch Show (2015–2016), and The Keith & Paddy Picture Show (2017–2018).

Francis was born in Beeston, Leeds, West Riding of Yorkshire, on 30 April 1973, and was brought up on a council estate in Old Farnley, Leeds. His father died aged 47 of cancer, whilst his mother, Pat, is still alive.

Francis attended Farnley Park High School (now The Farnley Academy). He later studied at Jacob Kramer College and received a qualification in graphic design. Before making his major television breakthrough, he was discovered and encouraged by television presenter Davina McCall, performing in-role stand-up comedy in a southern comedy club.

McCall landed Francis his first television role on Dom and Kirk's Nite O' Plenty, where he portrayed Bobby Stark, a man who gives tips on how to win over the ladies. The series aired on Paramount Television from January to July 1996. Francis' second television role was as Barry Gibson, a music paparazzo, featured on the early series of Channel 4's Popworld. Francis also starred as various characters, including Gibson, Keith Lemon and Avid Merrion in the series Whatever I Want, which aired late night on ITV in 2000.

In his early career, Francis did a series of shorts for Comedy Central (then known as Paramount Comedy) called Stars in Their Houses. Some of the shorts can be found on YouTube.

His major television breakthrough occurred when Channel 4 offered him a £250,000 deal to produce a series based on his television characters, such as his previous roles as Bobby Stark and Barry Gibson, and in 2002, Bo' Selecta! was born. The series featured Francis portraying a series of celebrities by wearing face masks to impersonate them, as well as portraying the main, non-celebrity character, Avid Merrion. The programme lasted for five series, airing between 2002 and 2006, however, the last two series were only loosely based on the original three. Series 4 was subtitled A Bear's Tail, and was based on another of his characters, The Bear. Series 5 returned to Avid Merrion and was called Bo! in the USA.

Following the axing of Bo' Selecta!, Francis took one of the series characters, Keith Lemon, and created a brand new show, Keith Lemon's Very Brilliant World Tour, which aired on ITV2 in April 2008. The show was a success, and subsequently, Francis created another new show featuring Lemon, Celebrity Juice, which aired for 26 series between 2008 and 2022. Lemon also co-hosted Sing If You Can (2011) with Stacey Solomon and Keith Lemon's LemonAid (2012) on ITV.

In 2012, he was the protagonist in his feature film debut in the self-titled Keith Lemon: The Film, alongside Kelly Brook. Francis has since presented and/or appeared in numerous other ITV2 programmes in character as Lemon, including Through the Keyhole (2013–2019), The Keith Lemon Sketch Show (2015–2016), The Keith & Paddy Picture Show (2017–2018), alongside Paddy McGuinness and Shopping with Keith Lemon (2019–2023). Francis had a cameo in Rocketman, the 2019 Elton John biopic, playing a shop worker named Pete.

Talking about a scrapped pilot for a Bo Selecta reboot, Francis retired the character of Keith Lemon, saying "Keith Lemon is, well, I'll never kill any characters off... I don't ever kill any characters off. Apart from if it's one that someone is really upset by. Then you don't do it anymore, because you only d**k about to put smiles on people's faces.". Francis continues to producing content for his YouTube, where he posts sketches in the vein of Selecta and other characters. In early 2024, Francis went on tour, starring in My First Time.

On 30 October 2002, at Allerton Castle, North Yorkshire, Francis married Jill Carter, a beauty therapist. They have two daughters.

On 4 June 2020, Francis apologised on Instagram, as himself, for his portrayal of various black celebrities on Bo' Selecta!. In the video description he added "Following recent events, I've done a lot of talking and learning and I would like to put this out there. I want to apologise to anyone that was offended by Bo'selecta. I'm on a constant journey of knowledge and just wanted to say I'm deeply sorry. #blacklivesmatter".

In interviews, Francis usually adopts one of his celebrity guises, being interviewed as Avid Merrion during Bo' Selecta!'s run between 2002 and 2006, and as Keith Lemon ever since. In an out-of-character interview with On: Yorkshire Magazine, Francis confirmed Avid Merrion's accent and dialects were inspired by his former tutor at Jacob Kramer College, Laimonis Mieriņš. He also pointed out Merrion is a misspelling of Mieriņš, and has nothing to do with the Merrion Centre in Leeds as some may have assumed. Francis has also been interviewed as himself for The Frank Skinner Show, Loose Women, Big Brother's Little Brother, The Museum of Curiosity, Friday Night with Jonathan Ross, and Sunday Brunch.
