Humphrey Lyttelton (b. May 23, 1921) is a well-known British jazz musician and chairman of the radio programme I'm Sorry I Haven't A Clue, and the cousin of Viscount Cobham, the 8th Baron Lyttelton.

Lyttelton attended Sunningdale Preparatory School and then Eton College, where his father was a housemaster (and, indeed, he had been born). At Eton he developed his love for jazz, forming a quartet there in 1936 after teaching himself the trumpet. After leaving school, he served in the Grenadier Guards. Following demob after World War II, he attended Camberwell Art College for two years.

In 1949, he joined the Daily Mail as a cartoonist, where he remained until 1956.

In the 1950s Lyttelton led the British "trad jazz" movement, a revival of traditional Dixieland and older jazz forms, from New Orleans to early Duke Ellington. In 1956, he had his only hit, Bad Penny Blues, which was in the UK charts for 6 weeks.

Lyttelton has presented The Best of Jazz on BBC Radio 2 since 1967.

In 1972, he was chosen to host the free-form comedy show I'm Sorry I Haven't A Clue on BBC Radio 4, a role he still performs.

In 2001, Lyttleton and his band added trad jazz elements to a free-form, experimental Radiohead song "Life In A Glass House" on the Amnesiac album.

As well as his other activities, Lyttleton is a keen calligrapher, as President of The Society for Italic Handwriting.
