Lee Cornes (born 1951 in Worcester) is an English actor.
He appeared in three series of Blackadder, as a talking extra, in two episodes of The Young Ones and in the TV show Bottom, as barman, 'Dick Head'. He made an appearance in the first episode of Filthy, Rich & Catflap as a binman. He also starred in children's drama Grange Hill as Mr. Geoff Hankin (1990-2002); provided voices for characters in children's television series TUGS, and featured in the Doctor Who story Kinda as the Trickster (1982). He also appeared in Red Dwarf as Paranoia in the series one episode "Confidence and Paranoia." He also appeared several times in the BBC Scotland sitcom Rab C. Nesbitt, once as a DSS Clerk and again as a barman in a highland pub.
His role as Mr. Geoff Hankin in Grange Hill is somewhat ironic as when Lee is not being an actor, he has been known to be a real substitute teacher in and around Sussex. 1998-99 he taught Science at Robertsbridge Community College.
He also appeared in the 2002 S Club Juniors video "One Step Closer."
He also is the lead writer for "Mr Bean, The Animated Series".
In an interview in The Times on 20 February 2010, Lee Cornes was cited as one of fellow comedian Sean Lock's biggest comedic influences. Sean said: "He’s not very well known but he is my main influence — he used to compere at the Comedy Store. He’s the comedians’ comedian. He used to be very unpredictable, which is a great skill in a comedian, not knowing where to go next. He also used to play the physics teacher in Grange Hill." 
In November 2010 he appeared as 'Dave' in Episode 6 of E4 comedy, Phoneshop.
