The 1998–99 rebel season in rugby union occurred when two clubs affiliated to the Welsh Rugby Union (WRU), Cardiff RFC and Swansea RFC, refused to play in the WRU-sanctioned Welsh Premier Division that season and instead opted to play friendly matches against clubs from the English Premiership. The two clubs' position came about after the WRU rejected requests by the club to pursue changes to the league structure in Welsh club rugby and in particular to set up a cross-border league involving other clubs in Britain, and the two clubs refused to sign up to a loyalty agreement with the WRU committing them to the current league setup.
