Piccadilly Jim is a novel by P. G. Wodehouse, first published in the United States on February 24, 1917 by Dodd, Mead and Company, New York, and in the United Kingdom in May 1918 by Herbert Jenkins, London. The story had previously appeared in the US in the Saturday Evening Post between 16 September and 11 November 1916.

The novel features Ogden Ford and his mother Nesta (both previously encountered in The Little Nugget (1913)). Nesta has remarried, to the hen-pecked, baseball-loving millionaire Mr. Peter Pett, and Ogden remains spoilt and obnoxious. The story takes its title from the charismatic character of Jimmy Crocker, Nesta's nephew and a reforming playboy. 'Jim' is called upon to assist in the kidnapping of Ogden, amongst much confusion involving imposters, crooks, detectives, butlers, aunts etc. - all in the name of romance of course.
