George Ramsay Acland Mills (1 October 1896 – 8 December 1972) was a British preparatory schoolmaster and an author of children's adventure stories. His whimsical tales often revolve around boys' preparatory schools in Great Britain and often involve sports like cricket, pranks, and mysteries, as well as a beloved pet bulldog, Uggles. He was born in Bude, Cornwall and died in Devonshire.
