Cyril Bibby (b. Liverpool, 1 May 1914 as Harold Cyril Bibby; d. Edinburgh 20 June 1987) was a biologist and educator. He was also one of the first sexologists.

Bibby was the third of eight children and lived in Aigburth, Liverpool. He was educated at Sudley Road School, Liverpool, Liverpool Collegiate Institution and Queens' College, Cambridge (BA 1935, MA 1939). He was active in the CU Socialist Society and the Union Society.

In 1958-59 he was the prospective Labour Party candidate in Barnet opposing Reginald Maudling (but resigned on moving to Hull in September 1959, just before the election was announced).

Bibby gained an MSc at the University of Liverpool in 1940 for research on Europe in Quaternary times, and a PhD at the University of London in 1955 for a thesis on T.H. Huxley. He wrote books and articles on Huxley, and on human biology, especially in the fields of health and sex education, and later on limericks. In 1936 he married Frances (Florence Mabel) Hirst (Girton 1932-1935, b.1914, d.1993); they had two sons and two daughters.

The Bibby papers are housed at Cambridge University Library.[3]
