Abingdon School is a day and boarding independent school for boys in Abingdon, Oxfordshire, England. In 1998, it merged with Josca's, a preparatory school four miles to the west at Frilford which since 2007 has been known as Abingdon Preparatory School, with both schools becoming part of the Abingdon Foundation. There are strong connections with the nearby School of St Helen and St Katharine in Abingdon. The twentieth oldest independent British school, it celebrated its 750th anniversary in 2006.
