The Toulouse International Rugby Masters were two international rugby union tournaments organised by Toulouse rugby club. The first, held in 1986 and known as the "Matra Espace or Matra Masters" for sponsorship reasons, is sometimes informally referred to as the first World Club Championships due to the participants within the competition representing seven clubs and one touring side from seven countries across three continents. The second tournament, held in 1990 and referred to as the Centenary Masters, marked the centenary of the club. Toulouse were the champions of both editions. The tournaments are viewed as the precursor to the European Rugby Champions Cup, in which Toulouse were crowned the winners of the first edition in 1996.
