Wrykyn is a fictional public school (which is, of course, a private school) in England, where many of Wodehouse's early school stories are set. Although the institution was introduced in the 1904 novel The Gold Bat, and would resurface in The White Feather (1907) as well as various short stories, Wrykyn is most closely associated with Mike Jackson. Their tenure at the school is recorded in the 1909 novel Mike, which was later subdivided into Mike at Wrykyn and Mike and Psmith (the latter half introducing Psmith when Mike transfers to another public school, Sedleigh). Jackson particular contributed to Wrykyn's already impressive reputation as a cricketing school.

Though Mike was the last work to feature Wrykyn as a central setting, it would briefly flit in and out in other works. Though not as ubiquitous a location as the Drones Club or even Valley Fields of the later stories, Wrykyn remained a vital landmark in Wodehouse's fictional world. It proved to be the alma mater of Stanley Featherstonehaugh Ukridge and several of his companions (notably Jimmy "Corky" Corcoran, Looney Coote, and George Tupper). Sam Shotter, protagonist of the 1925 novel Sam the Sudden, likewise attended Wrykyn. Later Wodehouse characters were more apt to have attended Eton or Harrow, however.
