Sir Pelham Grenville Wodehouse, KBE (/ˈwʊdhaʊs/; 15 October 1881 – 14 February 1975) was an English author and one of the most widely read humorists of the 20th century. Born in Guildford, the son of a British magistrate based in Hong Kong, Wodehouse spent happy teenage years at Dulwich College, to which he remained devoted all his life. After leaving school he was employed by a bank but disliked the work and turned to writing in his spare time. His early novels were mostly school stories, but he later switched to comic fiction, creating several regular characters who became familiar to the public over the years. They include the feather-brained Bertie Wooster and his sagacious valet, Jeeves; the immaculate and loquacious Psmith; the feeble-minded Lord Emsworth and the Blandings Castle set; the loquacious Oldest Member, with stories about golf; and the equally loquacious Mr Mulliner, with tall tales on subjects ranging from bibulous bishops to megalomaniac movie moguls.

The following is an incomplete list of fictional characters featured in the books and stories of P. G. Wodehouse, by series, in alphabetical order by series name. Due to overlap between the various classifications of Wodehouse's work, some characters appear more than once.
