Tales of St. Austin's is a collection of short stories and essays, all with a school theme, by P. G. Wodehouse. It was first published on 10 November 1903 by Adam & Charles Black, London, all except one item having previously appeared in the schoolboy magazines, The Captain and Public School Magazine.

The stories are set in the fictional public school of St. Austin's, which was also the setting for The Pothunters (1902); they revolve around cricket, rugby, petty gambling and other boyish escapades.
