John Yapp (born 9 April 1983) is a Welsh international rugby union player, currently with Edinburgh. He first played for Cardiff during the Christmas period in 2002. He made his first team debut against Ebbw Vale on Boxing Day at the age of 18 years. Despite his young age he had featured in 17 of a possible 19 games by the end of the season and had been called up to train with the Wales under-21 squad.
Yapp has represented Cardiff Youth and under-21s, winning cup and league medals and playing for Wales at under-19 level. Originally educated at Cowbridge Comprehensive School, he had first team experience with the Llantwit Major and Pontypridd clubs before becoming a full-time Cardiff Blues squad member.
In the summer of 2008 Yapp had discussions with club coach Dai Young and national coach Warren Gatland about the possibility of switching from loose head to tight head prop. He then headed out to Australia to play for Tuggeranong Vikings during the Northern hemispheres off season in an effort to become familiar with his new role in the scrum, before returning to the Cardiff Blues for the start of their domestic season.
In 2014, Yapp was listed as a replacement for London Irish during the Aviva Premiership round 17.
