Johnny Vaughan (born July 16 1966) is a British television and radio presenter. He is currently the presenter of the weekday breakfast show on London radio station Capital FM.

Vaughan's big break into television was on Channel 4 in 1993 where the public first saw his blend of quick-fire humour and impressions on the movie review show Moviewatch. Channel producers decided he was a natural in front of the camera and he fronted The Big Breakfast from 1997 until 2001, forming a partnership with Denise van Outen which proved very successful in terms of audience figures. In parallel he presented another movie show, The Johnny Vaughan Film Show. In 2001 he transfered to the BBC to present a late-night chat show, Johnny Vaughan Tonight in the same vein of American shows by David Letterman and Jay Leno. Viewing figures were not good, especially considering the wonders Vaughan had done for The Big Breakfast, and commentators suggested that the format was not best suited to the free-wheeling Vaughan. A sitcom vehicle 'Oribble was even more panned by the critics. In April 2004 he returned to the "zoo" format when he replaced Chris Tarrant as the presenter of the Capital FM breakfast show.

Vaughan has also been heavily involved with telethon charity drives such as Children in Need , Comic Relief and Sports Relief . In 2004 the BBC ran "a search to find the nation's best-loved sitcom" with a format that aped that of the 100 Greatest Britons. One celebrity championed each of the top ten sitcoms, presenting an hour-long special on why their favourite was the best. Vaughan was the presenter of the segment on Porridge.

Vaughan is married with two children. An avid supporter of Chelsea FC, he previously worked as a journalist and as an assistant in a video rental shop. In his early adulthood he served a prison sentence for an offence involving drugs.
