The World Series Cricket Cavaliers XI was a cricket team formed to play in World Series Cricket. Taking the International Cavaliers as its inspiration, the team was envisaged as a way of giving those players under contract to the WSC organisation, but not picked regularly for one of the three main teams (Australia XI, the West Indies XI and the Rest Of The World XI) regular match play and opportunities to win prize money. The team was formed in 1978, before the start of the second season of World Series Cricket, with a tour of Australia scheduled to take place at the same time as the main competition. This would see the Cavaliers play each of the other three WSC teams at a range of smaller venues around Australia between November 1978 and February 1979.
