He made his name on the comedy circuit in the 1980s, winning the prestigious Perrier Award in 1988 and best live act at the ITV Comedy Awards in 1991.
On TV, he appeared on shows like QI and sketch programme Now - Something Else.
Hardy was also an author and columnist, writing for London's ES Magazine and The Guardian newspaper.
Born in Farnborough, Hampshire, in 1961, he studied modern history and politics at the University of Southampton before embarking on his stand-up career. From the outset, he worked his socialist politics into his topical act.
He made his television debut in 1986 in Now - Something Else, an early vehicle for impressionist Rory Bremner. Hardy was a featured writer and also played the role of Jeremy the Trainee.
Hardy also appeared as Corporal Perkins in an episode of the BBC comedy Blackadder Goes Forth in 1989. Seven years later, he presented an episode of Top of the Pops.
Also in 1996, Hardy teamed up with comedian Jack Dee to write Channel 4 sketch show Jack and Jeremy's Real Lives. The pair would later work together again on I'm Sorry I Haven't A Clue.
Hardy became well-known for his comically bad singing on the long-running radio panel game.
He also fronted Jeremy Hardy Speaks to the Nation, a series of comedy lectures for BBC Radio 4, from 1993. Episodes were based around subjects as diverse as how to be a father and how to meet the challenge of the 21st Century. The show's 10th series was broadcast in 2014.
