George Henry Verrall (7 February 1848 – 16 September 1911) was a British horse racing official, entomologist, botanist and Conservative politician.

Verrall purchased the collections of several European dipterists: Ferdinand Kowarz (1838–1914), which contained many types of Hermann Loew (1807–1878); Jacques-Marie-Frangile Bigot and Pierre-Justin-Marie Macquart (1778–1855).

He published two books on the subject: A 2011 edition of Dipterists Digest was dedicated to an appreciation of his achievements in the field, on the centenary of his death.

His interest in botany and conserving wildlife led to Verrall purchasing tracts of Wicken Fen for their preservation.

He was able to rediscover a number of species of flora that had been declared extinct sixty years earlier by Cardale Babington, Professor of Botany at the University of Cambridge.
